Wow, thank you mate

[@Herr_Bone]

I watched this video, although I knew already everything you were talking about. Your voice is so pleasant. One thing I would like to add to your explanation on how to find the two cables of one coil. There is a method to find the corresponding wires without any measuring instrument except your hand. Just connect two wires and try to turn the motor by hand. If it is hard to turn, you found the wires of one coil. Easy to do, but perhaps a bit more difficult to explain why this works. And a bit funny, because it already has to do with power generation. :-)

[@kevinpersinger7957]

Thanks for the tip. Im gonna try that for isolating coils. I already identified it with a meter, but I don't always have that available(because i forget to plan sometimes). Good idea for a minimal survival if you need to generate power possibly too!

[@AKIOTV]

I'd recommend parallel wiring for small wind turbines; with the series config you'll reach the target voltage at a lower speed, but as the turbine efficiency goes up with tip speed ratio (how fast it rotates relative to the wind speed) and small wind turbines have a tiny radius so a high RPM is needed for a high tip speed, you really want this thing to spin fast. Therefore it's probably a good idea to try and wire it up in parallel so that the target voltage is reached at a more optimal RPM. If you don't reach the target voltage this way, you can always decide to go back to series. Very nice video btw!

[@ThinkingandTinkering]

[@oddjobbobb]

You never ever EVER cease to amaze! Thank you for taking the time to share your knowledge. I have a largish stepper motor from a surface sander. My younger brother overtaxed it and I replaced it from the nearby DeWalt store. I kept the old one, and now I know why.

[@Buzzhumma]

I used a mid drive 250watt bldc electric bike motor and used my bike to run my 50 watt tv with super capacitors . Worked great . It was the best energy harvester i made and i think the motor was perfect as it did not require much rpm to create the necessary 12 volts for the screen . It seemed to be around 100 watt i was producing for about 10 min and got 20 min telly time ! The key to its effeciency was using a 48 v ebike motor as the rpm could be low to get 12 volts out !

This is the best presentation yet involving the rectifier construction. I've taken apart some old CFL lamps to expose quite a few usable components. The rectifier is clearly visible on the circuit board. Unfortunately, the CFL is hard to come by these days. Lightbulbs (Edison base) now are all LED. Scavenging electronics has always been a hobby, but is limited by the surface mounted components in use today. When Radio Shack finally closed for good, it was a sad day. Well, they were going downhill anyway. At least components still exist online.

[@mikesmith2102]

I make small table top concrete displays as a hobby. You could connect a water wheel to the stepper motor which would power a small water pump. You'd have to spin the wheel by hand a few times to charge the capacitors to power the pump to get the water moving over the wheel to get everything started. You'd do away with the electric cord or the battery for the pump. To stop the flow you just stop the wheel until the water stops. That has some real possibilities for some interesting dioramas and other displays.

4 wire types are common, 6 wire types are common ( simply have 2 taps in the center ), 5 wire is pretty rare and have the center taps connected together as in your diagram. ( center taps allow for cheap electronics as you don't need 2 full bridges and the dead time timing and stuff like that ) These are fun to play with. They also deliver phase information when used as generators. If you hook up a led wo diodes and turn the motor with led instead of the axis that's very visible and could be used for rotating displays and stuff. A wind turbine with adds would be fun. These are also pretty good breaks. Tie all wires together and then turn the axis .. if you can ...

[@CraigLandsberg-lk1ep]

I have a 6 wire stepper motor, can you explain anything you can to me about it? Would appreciate any information 😅 thanks

[@Abdullu]

8:36 1N4007 diodes have a forward voltage drop of about 0.7 V. This means this voltage has to be exceeded before they will let energy through to charge the capacitor and have the LED light up, meaning unless a minimum rotational velocity is surpassed, the invested mechanical energy is lost in heat resistance and back EMF. Schottky diodes such as the 1N5819 have a lower forward voltage drop of about 0.25 V, meaning they can already be used at slower rotations to produce energy for the LEDs.

Seems like a handy little hand crank generator I might be able to use something-like this thanks for sharing, if you config a Zener diode at about 5 / 6 v across the C storage in reverse bias it will regulate the V to that V and you will have a rudimentary phone charger 6v~ As long as the Zener wattage is not exceeded but I think it would be ok , you could parallel the Zener for more wattage. Regards

cheers mate

[@ted_van_loon]

note that for the small one with 5 wires you can't connect them in series to increase voltage, since they have a shared center tap, so connecting that one in series will cause a short cirquit so actually reduce the voltage. those with 4 wires are fine, but the 5 wires ones generally have a shared common.

I enjoyed the video, thanks. I have 3 NEMA 17 stepper motors on my 3D printer. It is easy to generate a back EMF when moving the printer plate. I have to be careful to move slowly so I do not zap the electronics. I have seen the printer display light up. Not good. Testing for the wire pair which is a coil is easy to do without a multi-meter. Touch two wires together and try turning the shaft. If the wires are a coil pair you will feel resistance to the shaft turning. The splined belt comes in various pitches and widths. The belt should have the type, e.g., GT2, GT3, etc., but the pinion gear will not have a label, so unless you have purchased a specific pinion gear, it will be important to check the pitch on the pinion to ensure it matches the belt. GT2 and MXL pitches are very close but not interchangeable. My 3D printer is using GT2, but my latest project is an electronic step indexer for the wood lathe and it is using MXL belt, so I have to be careful not to interchange anything. Dave.

Hello Sir, At first thanks for sharing the wonderful information in the best easy way. I have few questions in my mind taking "Stepper Motors", hope you could answer them. Thanks in advance. Q1. According to you, which motor is best to generator electricity, and why? Options: A. Brushed DC Motor B. BLDC Motor C. Stepper Motor Q2. Referencing video, if I choose "Stepper Motor" as a Generator then which one to choose and on what parameters? We have, Stepper Motors with many different specifications such as a. Unipolar and Bipolar What I have learnt and understood watching videos on KZbin (I maybe wrong, maybe right, please correct me if it goes wrong) is that, Unipolar is easy to use and works faster than Bipolar. Secondly, we don't need to reverse the rotational direction in the Generator, so we don't need "Bipolar". So, we should use Unipolar in Power generation. (Please clarify) - Which one to choose and what are the advantages and disadvantages? b. Low / High Torque Second factor that I get to know about is the "Torque". In my learning, torque is the rotational force that is required to push or pull something. But in our case of power generation, we are not going to use Stepper Motor as motor but as generator which needs rotation at a speed to generate some voltage. We are not pushing or pulling anything. So, we should not consider or least consider Torque. Low Torque - High Speed (Please clarify) - What motor torque should be consider in Stepper Motor as generator? - Is least torque motor best suitable for power generation? c. Low/ High Input Voltage There are different input voltages available such as (12V, 24V, 48V, etc) according to different sizes and different torques. - Do they have any relation to the output voltage of the Stepper Motor as generator? - Which is best suitable voltage stepper motor to choose to work as generator? d. RPM (Speed) Get to know, Stepper motors have different RPM (10000, 6000, 4000, 3000, 2000, 1500, 1000 or lesser) Smaller Motors have Less Torque but High Speed As the size increases Motors have higher Torque and Lesser Speed -Is it correct, that, more the speed more the voltage we would get? (Please clarify) -What is the ideal speed or RPM that we require to generate the desired or correct output (voltage) for power generation? e. Steps (Less / 200 / 400 / More) As per my information, Steps are only required for the accuracy to work. More Steps gives More Accuracy and Precision - Do "Steps" play a role in power generation which I don't think so, please clarify? f. Single / Double Shaft - Do we have advantage of double shaft motor instead of single, in case, if we put 2 rotors to rotate the shaft of the "Stepper Motor i.e Generator) for more smooth operation and speed? (Please comment and clarify) g. Geared / Non Geared As per my information, gears gives more or high torque. - Do we any advantage of geared stepper motor in power generation which I don't think so? (Please comment and share your views) What all factors are important and must be considered choosing stepper motor as generator? Also consider, other factor that I have missed which should be considered choosing "Stepper Motor" as Generator. It would be really helpful, if you would share your views and comment or prepare a video considering the above points. Thank you once again for sharing the informational video and look forward more similar videos from you. Thanks

Stepper motors are the obvious choice. They are easy to wire and produce a good output. DC motors have brushe that degrade pretty quickly.

[@navalkishoresingal]

@@ArnookieVR Thankyou for your response, what about Brushless DC motors. Can you respond to any of the queries above for better understanding.

[@ArnookieVR]

@@navalkishoresingal I find stepper motors are better for hobby use overall. They are easy to connect and produce a good voltage evan at low speeds. This makes them ideal for DIY wind turbines & hand cranked generators. You would need to use a rectifier and capacitor on the output to get a nice stable DC output voltage. You can also use a car radiator fan for a super easy wind turbine. But you would need to increase the fan blades length. 😉

[@ArnookieVR]

Stepper motors are rarely rated on voltage. This is because of the nature stepper motors work by. Steppers are usually run on a low voltage. A NEMA 17 stepper would normally be rated 12 to 24v. But would normally be driven by 2v or even less ie when used on a 3d printer.

Hello Rob, great videos! I have to admit, I really got hooked up with the idea of building my own wind generator. Not for getting my whole household running of course, but for the experimenting around for fun. Idea is to have a couple of ugrinsky elements stacked on one axis with a bit offset (don't have a 3d printer 😅). A stepper motor would be my generator. Now, what puzzles me is the question if I risk burning the generator at better wind or what to keep in mind. Should I better go with the Thunderbolt generator concept and what wire diameter is good if doing so? Kind regards from Switzerland. Keep going!

Thank you for this, it makes things so much more clearly understandable, the unmistakable sign of a proper teacher/tutor. I have a 12 volt DC stepper motor about a foot long and 6 or so inches in diameter that I hoped to utilize as a source of motive power. I haven't seen it in over a year, or I would know the amperage, wattage, maker etc. Can this simple circuit be of use in pursuit of my quest? Is it feasible, on the whole, to hope that this motor might serve my purpose, to propel a trike of the Morgan variety, lightly laden? I am off in a day or so to retrieve it and thought I ought to ask. By the time you answer, I should know the proper answers. In either case, thank you.

Hi! Thank you for your video, I want to control the rotational speed of the motor using a changing resistance (I read somewhere I can do that) but to do that, I need to now the rotational speed of the motor - which I was wondering if I can calculate from the power output of the motor. Is that possible? Thank you!

Which is better to use as a generator. Stepper motor. Dc motor or 3 phase atlernator?

[@littleworkshopofhorrors2395]

He's enjoying his job again.😉 👍👍👍

[@ThinkingandTinkering]

I certainly am lol

[@youtubeworkshop3174]

Thank you too bro.. for detailed video

Hello Came across your channel and now subscribed. Would be nice to see how you would or could charge a 12v car battery as not everyone wants to power a house😂🤣. If possible may you fo one on connecting a stepper motor output to enable trickle charging of a battery. Great for small wind turbine projects or beginners.

[@JayHernan]

Awesome video! Do you have a guide on making a 12v battery charger out of one of these motors?

[@axelpissou1263]

thanks a lot for this video! when using this in a windmill for example, would it be best to keep the AC to span the distance to the house, and put the rectifiers inside, close to the charge controller?

[@pa_maj.MARTINI-van-MAN]

Yes, AC travels over distance better 👍

[@jesusisalive3227]

You could make a pretty nice hand crank emergency generator for charging phones and lights.

[@kenvoo7303]

Nice to watch your vid... Can i ask ? What type motor has least friction when generating output power ? Is motor with gearbox harder to turn on shaft ?

[@Aethalops]

Thanks so much! Super useful and inspiring. As a novice, when thinking about applications, I wonder about how to get a feel for dangers and limitations of this sort of project... e.g., Is there any danger of damaging the stepper motor by turning it too fast?

[@ThinkingandTinkering]

It's why I do so many small experiments mate - you get a feel but at low cost. Some folks complain I don't build enough big things - if I did that it would bankcropt me - do a lot of small - get a feel and then do a big

[@onemanriflemaker3873]

Oh yes. You got to stepper motors that’s properly awesome. These things are proper cheap. A CVT is a easy 3D printer job. This is proper exciting.

[@ThinkingandTinkering]

they are mate - that little one I showed with the gears is only £3

[@CDinkle]

Awesome video, I have a few large steppers laying around that now I know what to do with! What kind of amperage are you seeing with this set up?

[@ThinkingandTinkering]

not much mate - I was turning it by hand! Amp out put is going to be dependant on your input mate

[@DanaGould0]

You should see if you can find a broken hoverboard and salvage the wheel motors from it. There are a couple of youtube videos from 'DIY King' using one in a horizontal and vertical wind turbine. The horizontal turbine seemed to work well, but I think the vertical turbine needed to be geared up for better performance.

[@ThinkingandTinkering]

cheers mate - I tend to use what I stumble over so if one crosses my path you cane sure I'll use it lol

[@DavidHoegen]

I had a LG washer. It motor was a stepper motor. Realy big. If you turned it by hand it would power the light and buttons. Realy cool

[@ThinkingandTinkering]

LG - must look out for one

[@icarus_ap]

I going give this a try soon, I got some nema23 motor that I want to turn into mini wind turbin and wire then up to a MPPT solar charge

[@cecilcooper6210]

Thanks for simplifying that. Very useful.

[@ThinkingandTinkering]

Glad it was helpful!

[@donaldgroves5448]

Hey brother you're awesome, I've been building a generator for a few months now and I'm using the stepper motors and bridge rectifier method, I'm using a 12 volt dc motor wired to a controller wired to a solar panel and it works really well! I get more voltage out than I'm putting in, how could I go about possibly looping some of the power I'm getting out into the dc motor and eliminating the solar panel, or just using it to start the generator!

[@lamdo3003]

What happen if you use 🤔 1 of them run by the battery to pull another 10 of them? To charge another battery? Thank you sir.
