How to Reuse Washing Machine Motors - (The Simple Way )

[@ThePostApocalypticInventor]

Hey guys, new episodes about this topic are now online: Salvage a washing machine motor+transmission: kzbin.info/www/bejne/fpCth2qgia1nrbc Inside a Washing Machine Motor: Pinout, Teardown, Explanations and Experiments: kzbin.info/www/bejne/eaXYnYWnr9OVsKs

[@foxyrollouts]

cool

[@IdelcoEM]

I have searched internet how to hack, modify or reuse the motor control of a direct drive washing machine with the motor (brush less three fase motor and VFC) but didn't find anything. Could you make a video? Would be great to modify and add a potentiometer and some switches to control the motor free on speed and direction. Thanks!

[@kennethdegruchy5503]

Yes I am so interested in this also as I have a recovered modern washing machine motor and it's power / control board and have not figured out how to use it yet. I should try to aquired the service manual for the washing machine to perhaps provide better insight as to how the motor operates.@@IdelcoEM

[@ThePostApocalypticInventor]

BTW: I do NOT recommend to touch a moving transmission like this with your hands (with or without gloves). I was working on a handbrake, but couldn't finish it in time. I just wanted to put the video out, so I did this the quick and dangerous way. Please don't follow my example in this respect.

[@Altcapball]

+The Post Apocalyptic Inventor As far as I know, a short stick doesn't give you friction burn and slips out of your hand if its tugged away from you.

[@ultort]

+The Post Apocalyptic Inventor Thank for the video, but sure, near rotating things, I would avoid gloves and long sleeves.

[@Milosz_Ostrow]

+The Post Apocalyptic Inventor - Next time, simply use a block of wood as a "brake shoe", instead of your finger.

[@sirspikey]

+The Post Apocalyptic Inventor this is really interesting. I'm trying to find parts for building a beltsander (making knives) and was lacking a motor. But if you get this to work I will definitely salvage my old washer :P

[@ericsmith3411]

+sirspikey i c electric motors all over for a little a 10 buck that dont need a controller

[@MYNICEEV]

MORE! MORE! I don't care how long I have to sit in order to learn my friend. I am 65 and my yerning for knowledge is still the same as when I was 7. That's when I took my first radio apart to see how it worked. Magnificent video my friend. I like your ideas and can't wait to see what you come up with for control with DC supply. Next video. Please.

[@diabolicalartificer]

+Raymond Earle Ditto. I too am able to watch an hour long video. Not all Utube viewers have the attention span of a fly on amphetamines we are more like whelks ........ : )

[@MYNICEEV]

+Dr Wobble I totally agree my friend. I am 65 and continue to learn something new everyday. Thank you very much my new friend. I have subscribed. Have a great day.

[@prizedcoffeecup]

+Raymond Earle I get the same feeling now and again...just tonight I got fed up with an old notebook cooler of mine, disassembled it and repaired the section of wire that needed to be adjusted a certain way to make the fan work all the time, then replaced the bottom two large rubber strips with low heat hot glue so as to grip nicely the same way as the original two pieces of rubber that fell off.

[@MYNICEEV]

Awesome my new friend. Needs must when the devil drives.

Taunter Atwill Wow an Internet Hero... The funny thing is you would never say it to my face. Also you should be cautious who you speak to on the net like that you might just find your self hacked..... I have not lived under German Occupation but again if you read anything i said that happened 70+ Years ago most of that Generation is dead or retired there children run things now that was the other point your weak mind missed..... Anyway i am done with you as clearly your hatred towards all Germans of all generations blinds you to anything you can't even have a logical discussion or argument with anyone with out your uncontrolled feelings and emotions controlling you.....Pathetic

Part 2 to this video is now online! kzbin.info/www/bejne/l3O5k2ttoMqggKs

[@ThePostApocalypticInventor]

Just to clear this up: I'm aware that the term "frequency of revolution" or "frequency of rotation" is an uncommon term and that it must be strange for some people (especially some American viewers) to measure this physical quantity in Hertz (Hz) instead of RPMs. In Germany the words "Drehzahl" and "Umdrehungsfrequenz" are some of the terms used for this quantity. The letter one means literally "frequency of revolution". The Hertz (Hz) (1Hz= 1s^-1) is the SI-unit for frequencies and is the correct unit to be used in countries that have the "SI" ( also known as the "Metric System"). Any reoccurring event can be measured in Hz, not just oscillations. That includes revolutions per unit time! "RPMs" is a unit that is primarily used in the English-speaking world. It is not an SI-unit and that is why I try not to use it too often. The Metric system might still be uncommon in the general population in the US, but it is the excepted standard among scientist in basically ALL countries around the world. The RPM is based on the "minute" which is totally unpractical to use in many calculations, because all SI-units are derived from the SI-base units, including the second (s) as the SI-base unit of time. Using minutes only brings unwanted conversion factors into the calculations! 1RPM = 1/60Hz => 1Hz = 60RPM When talking about dependencies between "physical quantities" I try to use the names of the quantities instead of using "units of measurement". In this way you can make a statement without restricting it to one system of measurements: 1.Example: "When you step up the volts, the RPMs rise" ( bad practice) 2. Example: "When the voltage is increased, the frequency of rotation also increases" (good practice) When you still have doubts about describing the "revolutions per time period" as a frequency, just check the definition of "RPMs" found in Wikipedia: "Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min) is a measure of the frequency of rotation" en.wikipedia.org/wiki/Revolutions_per_minute I don't say that this is the only way to handle things, but the DMM that I use to measure the how fast the motor shaft is spinning puts out a reading in Hz, so why not just stick to that, instead of multiplying it by 60 all the time.

[@wither8]

+The Post Apocalyptic Inventor theconversation.com/why-the-german-language-has-so-many-great-words-55554 I was going through old tools my father had acquired over the course of his life (he is 60 now, so he doesn't really do much with them), and I found a lot of German HSS 2-flute hand-drill bits which was in my childhood tool kit he gave me ~20 years ago at 8 or 9. Dull but no oxidation or corrosion. I took them home, sharpened them quickly on my grinder, tried them out, and said in my best AvE impression, "Gehhrmann schkookum choocher."

[@stuarticusrobinson9319]

+The Post Apocalyptic Inventor Bravo, RPM is something of an anachronism really, most of the other time when dealing with scientific quantities we would use seconds as the time base. RPM has persisted probably largely because of the rev meter on car dashboards.

This guy is simply amazing. I sense a lot of consideration and sacrifice occurred to make videos such as this one. Many many thanks for this. Excellent demonstration and lesson.

[@markrent3269]

I understand about half of what you are doing ,but still find it both fascinating and educational, thanks

[@tyvole2387]

Thanks for doing these videos. I studied electronics at college ( a long time ago) and managed with that ok, but I never really managed to wrap my head around how motors, synchros and generators were used in the real world, 3-phase especially! These days. I'm more interested in making some tools for woodworking (such as sanders), so this stuff is really useful to me.

[@1000bluegsxr]

there is a electrical engineer in my family .he has never shared with me, other then he fixed cell phones for my cousin, as a hobby. your vid just showed me i know nothing.i do know it flows like water . yet i can fix cars, motorcycles,and any thing of properties and geometry.i can test millivolts yaaa. thanks for vid

[@mdoyle1981]

The induction motor's RPM is a function of frequency and the number of poles by design; not just frequency. 2 poles at 60 hz = 3600 rpm, 4 poles at 60 hz = 1800 rpm, etc. NEMA MG1 for reference has everything you'd ever want to know about motor design. Good video by the way!

[@nosafetyswitch9378]

Magnificent video! The thyristor circuit seems quite bang-for-buck because it seems it can power the motor quite stably! I cant wait for the modified circuit!

[@usethenoodle]

My Kenmore front loading washer suffered a mechanical breakdown a couple years ago. The spider which is the pot metal part your test bed is spinning, and attaches to the wash drum was broken in 3 pieces. The cost of a new spider was not worth it. It's only sold as a unit with the stainless wash drum. I couldn't see putting $600 into a decade old washer. So I took it to scrap recycle. Now, I'm pissed that I didn't extract the motor before I dumped the rest of it. I did look at it but I didn't know how to run it outside the washer. Great video! I want to learn all I can about this stuff. Thanks for doing the videos.

[@zoidberg444]

Fascinating stuff TPAI. I have learned a lot about electronics thanks to you. Thank you for sharing your knowledge with us. I would certainly watch an hour long video. But its much easier for you to edit and produce content if its broken up a little.

[@NavigatedChaos]

Your intro works. I didn't know your KZbin name but listening to the intro and watching it I thought "There should be someone who invents stuff solely for the use in the apocalypse." Then your title appeared.

[@azyfloof]

Duuude even if you put out an _hour_ long video on this, I'd watch the hell out of it :D I think many, if not most people here would agree. Would this work as an idea to get feedback of speed? Power the field windings directly with the AC, but pulse the stator windings with PWM. During the "off" cycle of the PWM, use back EMF from the stator windings to measure frequency of rotation. Perhaps that could be combined with the circuit you have there?

[@harrypehkonen]

+Azayles From what I understand, the field and stator windings have to be powered with the same kind of current (AC or DC). If they were powered differently, the attraction/repulsion between them would be unpredictable (dependent on frequency of current and revolution).

[@scottfirman]

the Cubans have cornered the market on reusing washer motors,there is even a book made available documenting what can be made using discarded household appliances. Apparently, Castro gave his blessings on publishing a booklet to be released to the general populace incouraging his fellow countrymen to show their spirit of inventivement and later had a book published showing what others had come up with. Apparently there were two published versions made,one after the other became so successful.Go figure. I do not recall the name of such books, but I am sure with a little internet surfing you will find said publications.

[@ThePostApocalypticInventor]

+scott firman Yeah they also made a documentary about those guys. Necessity is the mother of invention.

[@wither8]

+The Post Apocalyptic Inventor During the Cold War the US (and as a result, the US allies) imposed an embargo on Cuba preventing the import of new cars (there was no domestic car manufacturing market within Cuba). As such the Cuban populace have had to make due with cars of a vintage nearly 50 years old. (Which, in some ways is good, because I'd imagine their trash output must be way lower than any other 'developed' nation, I digress though.) Now that the US-Cuba foreign relations have (somewhat) resumed, there is a lot of hype amongst vintage car enthusiasts within the US, as their innovative mechanics had to go to extensive lengths to keep those cars on the road in relatively stock configurations. (Instead of using hydraulic lifts, they just dig pits; instead of using fancy TIG/MIG welding setups with Argon, they have DIY stick-welding, etc. I'd be curious to see how they domestically manufacture their own primers/paints/clear coating that adhere to aluminium)

[@WobblycogsUk]

Great video, really interesting stuff but please please please stop touching the belt when it's running! One time you'll get your glove caught and a few milliseconds later you'll be missing a finger or worse.

I used a wrong terme when describing the setup. The belt is not "toothed" since it doesn't have any "teeth" :D

[@SlocketSeven]

+The Post Apocalyptic Inventor The correct term is apparently "Ribbed", just for future reference. Great video.

[@telephonetelephone9040]

HI MR P.A. Inventor, I see some videos online on how to change the washing machine motor into a power generator. They use an older upright type of washing machine. Can you perhaps tell me step by step how this is done with a normal washing machine?

[@ThePostApocalypticInventor]

+Telephone Telephone Please give me some links to those videos. Otherwise I won't be able to tell you what exactly is happening there.

[@raedy07]

[@joshuawise6518]

I can see a nice 2×72" belt grinder being built with that rigid cast iron frame, it almost looks designed for one

[@TheMarcball]

[@patrickfitzmichael5940]

You sound a little bit like Marvin Martian. No insult intended. We like it.

[@triumphmanful]

[@mattiaiezzi9381]

As always, great video! Hoping that you'll use the tachogenerator at some point. There's even a Motorola IC for that, the TDA1085C, but maybe you were thinking about discrete logic, which is great!

[@ThePostApocalypticInventor]

+Mattia Iezzi I have a TDA1085 and I will use it at some point, but the problem is that the TDA 1085 has been an obsolete device for many years. It is not manufactured anymore and people probably will have a hard time to buy one. At least here in Germany there are only a few private individuals who sell the rest of what they have. They usually want to have 10€ or more per chip. So it really is not my first priority to use a TDA 1085. But I'm working on a design around the TCA 785 that will probably be able to use the tacho generator's output as a feedback signal.

[@colt4547]

Great video. Back-EMF controllers have eluded my own personal study. I look forward to the next video.

[@voltlog]

Really nice educational video, I like the way you present the theory of operation. Thank you.

[@soupflood]

A year ago I assembled a bench grinder from an universal motor like this, commanded by a triac dimmer for vacuum cleaners. The dimmer's potentiometer is connected to the contacts of a relay, which is triggered by a transistor. The transistor is triggered by the tacho through another potentiometer and a diode bridge. _The relay needs a separate power source._ It's easy to build, but it's also noisy and the no-load faster speeds aren't constant. Under load though, it runs okay. I still use it.

[@taunteratwill1787]

+soupflood I'm so happy that you got this of your chest, no go back to the drawing board and make the speeds constand under all conditions dammit.

[@soupflood]

Taunter Atwill You will need a programmed microcontroller then, unfortunately.

[@taunteratwill1787]

So? Is it expensive?

[@soupflood]

Taunter Atwill Not at all, but programming it requires some knowledge that I don't have. I know, I should learn it, and I will - sooner or later.

[@Felix2417425]

16:13 Why not add just a full-wave rectifier and than you can use both half-waves of input sine wave?

[@ThePostApocalypticInventor]

+Felix2417425 Yes that is the general approach to make a full wave design, but the hard part is to adjust the rest of the circuit after having added the full wave rectifier. Believe me: I have done nothing else for the last two days...

[@mkosachuk6530]

I have virtually the same motor only it's from a whirlpool washing machine. I have the "three phase converter" hooked up but I need to know what to hook the three smaller wires coming out of the "converter" to. I want to get it on a dial like you have it so I can use it on a honey extractor, as I'm new to beekeeping and am trying to do things on a tight budget. I appreciate your help. I also have eliminated the other components in the machine by means of the diagram provided from whirlpool. Thanks again!

[@rocketman221projects]

What kind of vacuum cleaner did you take that speed controller out of? Every one I have taken apart just connects the motor directly to the mains.

[@1pcfred]

+rocketman221projects I am beginning to get the idea that they have much nice stuff in Germany than we have here.

[@ThePostApocalypticInventor]

+rocketman221projects I don't remember the make and model. I have salvaged lots of cheap vacuum cleaners and they ALL had a phase fired controller. It's standard here :D

[@1pcfred]

The Post Apocalyptic Inventor In the US vacuum cleaners just have an ON-OFF switch. So they're all, or nothing.

[@ThePostApocalypticInventor]

+Paul Frederick I guess that's not really a problem. Most people operate their vacuum cleaners at maximum power all the time anyway. So in most cases it's just a cheap but useless feature. But for a scavenger like me it has been a good source for simple yet reliable triac-circuits.

[@1pcfred]

The Post Apocalyptic Inventor yes I would love to have access to that hardware myself. Often cheap speed controllers have lousy heatsinks in them, and the switching component tends to burn out. At least that has been my experience with the couple I have gotten my hands on. There's usually a piece of aluminum sheet metal pop riveted to the Triac, or SCR. So pretty inadequate. Also I vaguely remember there's a fundamental difference between a dimmer, and an inductive speed controller. You might want to highlight that in a video. Maybe it is a flyback diode in the circuit? I forget.

[@TheMetalButcher]

Is that high-pitched noise around 15 minutes when running from the controller or from electronic pulsing noise? I can't ever remember hearing a washing machine near that noisy.

[@ThePostApocalypticInventor]

+justfakeit888 It's the motor itself. Universal motors are very noisy. If the motor is still inside the enclosure, the sound is just a little more dampened.

[@douro20]

Have you ever looked at some which have inverter drive motors?

[@pellefant9833]

So according to your advice I now have climbed the utility pole and made a temporary platform to complete my copy of your circuit. I'm ready to do the connection to the mains - but which end do i connect and where?

[@DrHarryT]

What about the tree-phase motors? They use switching mosfet's to generate the correct frequency using the 120VAC line, turning it into DC first.

[@c.j.1089]

I never realized using washing machine motors were such a pita. I figured you could use the OEM motor controller by finding a potentiometer or frequency control somewhere in the circuit.

[@muh1h1]

please be careful, we don't want you to lose a hand...

[@ThePostApocalypticInventor]

+muh1h1 Yeah I know I should not put my hand anywhere near it...

[@muh1h1]

The Post Apocalyptic Inventor At least not soo close, i don't want to imagine your finger being pulled in there, that would be pretty uggly...

[@j.mcinen4587]

+muh1h1 I've seen the tip of a thumb hanging by a thread after it went through one of the belt pulleys on a car engine. Luckily he had his pinch hold in a position where it allowed enough articulation in the wrist to match the twist, or going round the wheel would have twisted his finger into a twizzler.

[@mickstephenson]

+The Post Apocalyptic Inventor However if you do do it, you gotta still post the video.

[@1pcfred]

+muh1h1 I kept on telling myself, He uploaded the video, so he must not have hurt himself too badly making it. But I still had a lingering doubt throughout the whole production every time that motor, and pulley spun up.

[@dashlamb9318]

This proves that knowledge and wisdom are sometimes mutually exclusive. It is unwise to subject one's hand to such danger!

[@SteinErikDahle]

Long videos are great! Really looking forward to the next one!

[@MsDowloader]

I was thinking about adding full bridge rectifier before the thyristor controller, then the negative side would be the positive side and you should (in theory) have more power.

[@shannonlove4328]

The problem here in North America is that our three-phase 220v circuits are only in the kitchen and the washing room for the big appliances. I've got a pile of 3-phrase 220v motors which I could easily use, in my kitchen, after pulling out the stove. They still grind those motors out because they're cheap not needing permanent magnets or regulator circuitry.Since the logic of motor field switching comes from the grid itself, we're kinda screwed. All the other motors are 120v with permanent magnets. That makes it hard to salvage from a 110v to 220v. One of the few benefits of WWII, when we rebuilt the power grid, we built it on 220v.

[@zx8401ztv]

I wished all washing machines were made as good as the siemens, that cast bracket looks really great for experementing and perhaps inclusion into a project :-D . I enjoy your teaching method, showing the reasons for each circuit and improvements. I would imagine that hall effect sensor output would be converted to a feedback voltage that can be used to trim the motor supply, much like in switchmode power supplys :-).

[@ThePostApocalypticInventor]

+zx8401ztv Yes it's true. Many washing machines these days are much cheaper in build. Even Siemens is now producing some rather cheap machines. The old Miele machines are even more rugged than the their Siemens counterparts. There must be about 40kg or more of cast iron parts inside older Miele machines. But Siemens is the only manucaturer I know, that uses a fram that holds all the interesting parts together. And yes: The circuit that I was working on from the beginning is supposed to work just like an SMPS. Only that instead of the output voltage. it's a signal from a Hall sensor, or from the tacho generator, that is used as feedback. But at this point I'm thinking that Back-EMF is really the simplest way to properly stabilize these motors with the least effort.

[@zx8401ztv]

+The Post Apocalyptic Inventor Why make it difficult for yourself, you can go ultra complex but its just a motor, and not a precise one at that. Simplicity has value :-D

[@ryandavidsheasby4028]

Minor mistake at about 5:20. The speed difference between two wheels like that is dependant on circumference not on diameter.

[@HaLo2FrEeEk]

I salvaged a washing machine motor and the circuit board that ran it had a PIC microcontroller on it (a pic16c56). I desoldered most of the more useful parts from the circuit board before thinking about whether or not I could just jack into it to control the motor. I have a few ideas for what I'd like to do with the motor, most prominent being a lathe, belt sander, or bench grinder/buffer, or perhaps building all of those and having the motor be movable between them. What I'm struggling with is driving the motor. I got it spinning using "the simple way", but it's not being controlled, just spinning unloaded. I'm not wealthy, so I don't really have the means to buy parts to put together a control circuit, but I've salvaged quite a but. The thing I struggle with is the triac/diac use in circuits. What the heck is a diac? I've taken apart many AC control circuits and looked up part numbers but I've never come across anything that says "diac" in the datasheet, is there another name for it, or another something that can be substituted?

[@LT89NL]

It's a kind of diode, and is relatively common in AC regulation circuits, such as light dimmers, and motor controllers. Look it up on wikipedia and you'l see what a Diac is.

[@HaLo2FrEeEk]

I just want to know what to look for on the circuit board. It seems like all the circuits I've taken apart that use triacs never seem to have a diac on board as well.

[@MineOfTheLegends]

Image result for diac symbol The DIAC circuit symbol is generated from the two triangles held between two lines as shown below. In some way this demonstrates the structure of the device which can be considered also as two junctions. The two terminals of the device are normally designated either Anode 1 and Anode 2 or Main Terminals 1 and 2, i.e. What is a DIAC | Diode Alternating Current | Radio-Electronics.com www.radio-electronics.com/info/data/semicond/diac/diac.php

[@MineOfTheLegends]

I hope the answear of DIAC can make Halo2FeEk happy

[@Hongqie]

That rugged cast iron frame are just perfect for belt sander

[@SwingingTheDead1]

looks like that setup would work really well for a band saw. Or, like you said, a sander. thank you for the video

[@shanesmaineshop]

Very interesting. I have a motor from a washer but not the rest of the parts in your video.

[@nunyabusiness7630]

Running in closed loop with a controller can maintain the prime mover despite a changing load providing the load is within the power range while taking into consideration duty cycle or any reductions of output.

[@BogdanSerban]

Can the thyristor circuit be used for power tools like angle grinders, drill machines?

[@ThePostApocalypticInventor]

+Bogdan Serban Yes., but only if the do not have an integrated phase fired controller already.

[@BogdanSerban]

+The Post Apocalyptic Inventor the angle grinder doesn't have any speed controller, and the drill had one but I had to remove it since it was broken. I have used a light dimmer which has a triac circuit, but at low speed I can stop the drill very easily. So your circuit might work great!

[@ThePostApocalypticInventor]

+Bogdan Serban I have tried to operate oe of my power drills with the circuit and it worked great. But the next circuit that I will present will be even better.

[@HaLo2FrEeEk]

Excellent video! Just what I needed. I recently salvaged a washing machine motor, along with the circuit board inside it. I plan on making a multitool with it (bench grinder/buffer, belt sander, maybe other things). I'll keep these bookmarked for reference later. Thank you!

[@The52brandon]

Thank you soooooo much for combining your isolation transformer with a variac. My friend that's been helping me to plan and design my workspace and tools. My original plan was to install my own dedicated breakers, running new, thicker, better insulated power wires from the breaker box into an isolating variable transformer and finally out to multiple outlets of 110-125 and 220-250 (probably through use of taps on the secondary winding. Since I'll probably only be building my tools for the higher voltage, and using ready-made devices on the 110-125V outlets, therefore really only needing the finer adjustments on the higher voltages).And he said an isolation transformer cannot be combined with a variable transformer. It's a weird statement that I couldn't concretely disprove with Google quickly. But your creation/use of one takes care of that for me. So now we can get back on the same page designing it rather than letting such a small detail split our ideas so severely

[@albertcrowe8960]

Do you have a video on using a motor of some kind attached to a saw blade for making ones own Sawmill perhaps?

[@MrHrKaidoOjamaaVKJV]

What uses , applications purpose do these recycled Washing Machine motors have?

[@Swiitchs]

Your intro is just sooooo charming

[@markfothebeast]

8:09 - Quite possibly a functional electrical supercharger. If it can handle that rotation speed.

[@swimon]

Just a very small correction : This belt is called a groove belt. Tooth belt is something else.

[@I.P.T.V.]

I suspect that when you say "isolation transformer" you may actually be referring to a standard variable voltage transformer ("Variac".) A variable transformer may or may not provide isolation from the line, so your description may be vague-but-correct. But most don't. If it's a standard Variac-type variable transformer it won't provide any isolation from the line and this can be a critically important difference regarding safety in some situations.

[@bhnjhbjhbkgkkvhnhmbm]

Does the starter coil has a purpose after starting the induction motor?

[@birthcertificate7223]

you could use the motor to increase the temperature in forges, modifying the motor to include a fan which blows into the fire.

[@tonykempson4331]

Thanks for the information presented here about universal motors, and the great youtube channel.

[@JamieKugelmann]

Is there a way to use one of these motors as a generator/alternator?

[@mickstephenson]

I feel like this motor would be great for powering a bandsaw. Looking at what's available round here (the UK) for "spares and repair" there are no Siemens washing machines available, would you find a similar set up inside a Miele machine?

[@cletusspuckler2243]

Yes , this kind of motors are mounted in most of the brands of washmachines nowdays .

[@deltaxcd]

There is one super simple way to stabilize rotation: Just connect motor windings in parallel instead of series like it is now. Parallel excitation motor will provide very stable rotation frequency which also can be regulated by adjusting excitation winding current. there may be problem with very powerful startup as it will draw enormous current during startup and also it may be that excitation winding cant hold full mains voltage so you may be required to connect some ballast in series. My guess is that motor will run in about 5000rpm but it will have very high torque and it may tent to overheat. But all that should be tested to check how well those motors work in parallel excitation mode.

[@ThePostApocalypticInventor]

+deltaxcd I have tried that and it's not that easy because the field winding is not designed to be supplied by the line voltage directly. The current flowing through it will be too high.

[@deltaxcd]

The Post Apocalyptic Inventor Did you really tried that or you just guess? I had plans to test it myself. It is expected that mains voltage may be too high for that winding, but you can reduce that current is some easy way like connecting restive basalt or some transformer If you use variac you can control motor speed

[@ThePostApocalypticInventor]

+deltaxcd I actually tried it a couple of months ago. However: I will perform some experiments under more controlled conditions in the future. I will compare series wound, shunt wound and separately excited modes etc. For now I have enough work as it is, prepairing and testing various control circuits as we speak. The good thing is, that they will be usfeul for other devices with build in series wound motors as well.

[@Metroid1890]

Where can I find that kind of boxes? 11:00

[@mjvien]

I have a question for you. Can you tell me how to remove the drive end bearing? How to manage with the drive end part diameter that is bigger than the bearing diameter? Is there a way to unscrew the drive end or do I have to use an extractor of bearing ?

[@slicktires2011]

Do you have a video with the basics on electric motors and controllers? such as DC vs AC motors?

[@berritandersen288]

Genialer Kanal, endlich hab ich Dich entdeckt :-) LG, Berrit Andersen

[@kermets]

Could these motors be used as a generator if doubled up or more and run by small petrol motor to give nice voltage for a computer etc?

[@michaeld954]

I was thinking of using the pulley to make a saw mill 2 of them would hold the blade and the motor would attach to the shaft on the back side do you think it would be strong enough

[@toastersock]

The circuit diagram shows a 100 micro henry 5 amp inductor where might I find one of these or is it fairly easy to construct? Also what function does it perform in the circuit?

[@38911bytefree]

Love the last circuit, simple and elegant. Thanks

[@edonmorina5809]

when will the next video come? Full wave rectifier. I have the same motor I couldn't use it. Thanks for the video.

[@ThePostApocalypticInventor]

+Edon Morina I have been working on it every day since I made the last video, but the circuit isn't finished yet. But I'm possitive, that I will succeed within the next few days.

[@edonmorina5809]

I wish you the best.

[@360totalcontroltijuana4]

I would like to use a motor from a washing machine as a gate openner, to you think the would be sufficient and reliable?

[@robertburgy7735]

I have a bench grinder plugged into transformer. I would like to be able to slow it down for sharpening purposes but if I slow it down the power is gone and it becomes unstable as you say it. When I stop applying pressure to it the speed takes off. Is there a simple device for slowing it down without loosing the torque needed to do the task It would be nice to use your washing machine motor that can be stabilized to turn a diamond coated disk possibly.

[@bobbytsoutsias6739]

Verry good! Is it possible to build adrone ? Is it possible to buy a gadget drone with g sensors and sonars and "blow up" to a big one to carry one or two persons?

[@GabrielM0rais]

Hi there! So, I found recently that a Samsung brushless washing machine motor works with 93volts and 2.8 Amps (Washing) and 218v + 2.0 amps (spinning). I think that if you increase the amps and decrease the voltage, you can get more torque even for a universal motor.

[@FUGYOO]

NSA will be coming for you. Very creative. Thanks.

[@alexanders860]

Thank you for the video! Is there's any way to get the schematic of the last device - the constant speed controller please? I would like to experiment with my salvaged motor a little. Thank you!

[@charleswhitehead7441]

Why, if you have a tacho sender on the motor, have you bothered to put a hall effect sensor seperately?

[@bobsurrey6686]

Is that motor setup from a Bosch washing machine?

[@CT-se7rg]

Nice video, can u also make some kind of lift system with a washing machine motor? And how much kg's would it be able to torque?

[@benflora5580]

How to make pulley out of beer can

[@synocate5602]

Would you be able to demonstrate something like this but with a DC treadmill motor perhaps?

[@ThePostApocalypticInventor]

+synocate Waht do you mean? Are you asking me to make a video about a DC treadmill motor? I frankly don't have one of those and I never salvaged one so far.

[@Re_Kitty]

+The Post Apocalyptic Inventor Yes, that is what he was asking. I love your videos by the way! Hope to visit beautiful germany some time!

[@1pcfred]

+The Post Apocalyptic Inventor Yeah I missed the boat getting treadmill motors myself. I remember seeing those things on practically every street corner when folks got tired of them, after the fad died out.

[@redataleb9420]

Hi, can the motor be used for plastic shredding ?
