12v DC to AC ELECTRO MECHANICAL Generator REPAIR .. HOW THEY WORK .. solar lithium powered?

We dive into a relic of DC to AC power generation. This may be EMP proof as it's so simple.
You need a Kill-A-Watt meter THEY'RE FUN: amzn.to/3w6gXPd
THOUGHTS:
Redi-Line DA12L1600 dynamotor has a staggering price tag of $4000..... Yes 4 grand but it may be EMP proof as you could easily bypass the sensing circuit with a toggle switch. I'm not sure of the efficiency but I would suspect it's low due to the 20amps DC required to just spin/idle the unit. However I guesstimate it pulls around 150-200amps/12VDC(can't be over 200amps as that is the fuse rating they call for) to deliver 15amps/110VAC. So that's 1800-2400watts of DC to produce 1600 watts of AC. So 66-88% efficient; ballpark 75% efficient... Compare that to the modern efficient sine wave inverters and they are low 90% but they also draw power when nothing is pulling/they are idling(old inverters are 80%). Though this spins and is the same sine wave power as the power company makes, it has one HUGE drawback: HZ and voltage are dependent on a constant 12.6V input. Lower/raise the DC voltage and the HZ/AC voltage swing with it. I think a large lithium array would stabilize this voltage. Love to hear your input.

[@fourfortyroadrunner6701]

These type machines have been around since the 1920's. "Motor generators." Usually other way around, AC line powered, with various DC outputs, sometimes high voltages for vacuum tube anodes. In WWII "dynamotors" were popular particularly aircraft, typically 24VDC in, and various DC outputs for vacuum tubes. Welders used to be like these, AKA 120/ 220 in and DC welding voltage out. in 65--67 a state patrol had a tube, trunk mount radio and the tx was dynamotor powered. He had to remember to key the mike, wait a second for the dynamotor to spin up before speaking. You could always hear a tiny bit of whine in the signal.

Bought a product called Redi-Line for decades in our fleet. Is so quiet and reliable. After retiring, I even bought two Comcast cycled out assets. It’s my the generator fails, I have these. One for me, and another for a good neighbor. Just use jumper cables to power and the 120v to heat their home in the winter (gas). Remember the old Military expression, “One In None”.

[@dt7377]

They certainly are interesting critters. Used to be way more common than you think. All of the old, old, really old (1940s to 1960ish) Motorola two-way radios used to have them. They took the six volts from the battery and produced either six or nine hundred volts for the plate voltage. Naturally they were old tubers back then. Amazingly they can still be found in service today. One police department used one up through the late '70s for their police department base/disparch radio. You knew who it was because you could hear the dyno spooling up as the tubes came to life.

I had that exact model in a 1984 Bluebird WanderLodge motorhome (I have some clips of the motorhome on my channel). In that application the purpose was you could have some 120 volt appliances as you were driving without having to run the auxiliary diesel generator - in today's motorhomes those duties would be performed by an inverter. It wouldn't run an air conditioner but it would pretty much run anything else in the coach except for the electric water heater which you didn't need because that was heated by the engine when you were driving. Mine had been taken out of service and I never tried to get it working because since I live in Texas I always use the air conditioners so I always had the diesel generator running...

Got a smaller 600w 230v version of this, something to note is that they won't kick on with a small load, so somethings like laptop charger, phone chargers, etc won't trigger, so having a 40w light bulb on hand to trigger it is a way around it. Once they are running it's no problem.

Always had a power strip , liberator and a few other adapters With me as well , including what looks like a short extension cord with the three females on the end , but was about six inches long early power strip liberator. Something one should always have in their travel kit or laptop bag et cetera for sure. You know where all outlets use. But you can unplug something for a second to plug something else in. Just put in a power strip Liberator and you've got your extra receptacle. Power strippeding the app works great. Also I have a horde which has the piggyback plug that goes two a Is female.

[@aaronbrandenburg2441]

What are the largest motor generators?I've seen well besides that for elevators. This was four a electrically operated carloon. The power was derived from a motor generator set. If a rumor correctly the output was one hundred or more amps Around forty someodd volts. Largest soul noise I've ever seen.Oh you should see the relays on those puppies. I got. To be up in the tower.And boy, no things were impressive even just a solemn noise themselves and a relay contacts on the top huge DC.A arcs when they fired off. Hate to point out how long But four services would be near on the contacts. Apparently those relays are improved by other relays. If I remember correctly the hero log was played by a paper roll. I think. This could possibly played from the oregon council if i'm not mistaken. But the roles replayed automatically but could be probably fast.I know but they said they were having problems with the system. I did get it working That is the part where it was interface with the Oregon console.That was not operational. Had something to do with couple of relays or the switch can't remember. Long ago it turns out there was a hand-drawn skyrannic for the system.That's the way I had Reverse engineered to maintain the system. The bells or trims depending on your Point of view we're actually very long essentially especially shaped tubes. Not bells like one would think in a traditional Sense. Although. There are electrically operated traditional bells. Where the clapper is Electrically operateed.

[@Fastcar5000]

On some ships they have motor generators sets (MG set) like this on a larger scale. They are often used to change the phase from 60 hz to a different value for some equipment like radars and radios.

[@sixtyfiveford]

Very cool.

[@aaronbrandenburg2441]

I'd say four hundred hertz add one of the standard Is volt juice. By the way, some missiles, the guidance system has 3 phase and the wmissile.Would actually contain a Motor generator for obtaining the three phase from the aircraft. And also even if the missile was just on board this motor generator would be running whenever there was power or at least to the missile itself Even when it's just On there and standby for use , it's still powered up. There is a video on this somewhere on youtube about the territory of the missiles guided systems and one is interested in trying to find it. Also, motor generators are often used to get other frequencies go from AC.2 and apparently there were some systems out there.That could be used either direction.I know it's niche case , but it was Done in some applications. And not just different voltages but going from single phase to multiple phase as well And wouldn't be surprised if there was some old units that would run off toothpaste power.And yes that's a thing. Apparently. Some places still in philadelphia do use this And the buildings are hard wired for Two phase. Note , this is not the same as webphase as in One twenty volts and two twenty. Is too entirely different animals. It's certainly the 2 phase is 2 outer phase separate lines of 120 V.There is no 220 in the systems, at least as far as the general use.I'm not sure if there's any otherwise for higher voltage for heavier equipment or not. Limited Is knowledge . The main thing for polyphae's systems is large motors are more feasible. Of course, other way.I'll just but the big thing back in the day was motors. And since , since single phase was harder to get them started and of course , power requirements for larger ones. Essentially , if you can You've got a already quarter quarter quarter.Rotating magnetic fieldoes you have you're starting . At least theoretically.Of course , there's all sorts of other arrangements , but it's a general idea. Have seen play radio gear with the Darna motor. Once saw a zillion radio set with one of these Was kind of surprised at the input voltage 40 someone volts had to have been farm power and yes, that was DC.In

[@bardmadsen6956]

What a cool contraption, I love finds like that and figuring out what went wrong. I know a guy who runs AC power tools off alternator(s), on his older truck he was welding from the alternators and that poor big block Ford was being dragged down to its knees, and it sounded like bees. Yeah, resistance loads draw one hell of a load, kind of makes one turn off the coffee pot as soon as possible.

[@sixtyfiveford]

That's a unique setup.

[@Captionmarvelous]

I have a smaller version of what you have there. I think they would have mostly been used in ambulances and fire trucks to run the radios and other electronics in the days before wide use of transistors. They use powerful magnets in the field in place of an actual field winding. Mine took at hit and some parts of the magnets broke lose and jammed the motor/generator. I pulled all the broken magnets parts out, cleaned it up and it still does full output with about 1/3 of the magnets gone!

[@mikemorgan5015]

Used to have these in our M577 artillery fire direction tracks. Basically an M113 armored personnel carrier with more radios and a higher ceiling. You have to remember with these things that because it's 12v in and 120v out, that means over 10x the amps on the 12v side of whatever the 120v load is. So go heavy on the low voltage wire size. Think welding leads. I say "over" because they are not, of course 100 percent efficient. All they really used it for back then was running a Mr. Coffee and a Norelco shaver. Those tracks had 24v systems, so it was only 5x the amps. But still.

[@stephenmitchell4393]

Yes, there are two motors on the same shaft. Ordinarily, they are run in parallel, (watch your polarity) for 12 volts, and series for 24 volt systems. I installed several of these in buses during the late 70s to operate an A/V system. Output frequency stability however, sucks.

You are the wizard of fix-it. As the motorhome guy said, nowadays an inverter would provide that function, but I know that they also have an energy cost to function even though they're not turning any motors or generators. I wonder how efficient this method is compared to an inverter, just speaking of the energy cost of the device to make 120 vac out of 12 vdc, not counting the actual loads being placed on either one. Would it be a stable enough sine wave and frequency to run computers and such? Great video. Thank you.

[@sixtyfiveford]

I'm not sure of the efficiency but I would suspect it's low due to the 20amps DC required to just spin/idle the unit. However I guesstimate it pulls around 150-200amps/12VDC(can't be over 200amps as that is the fuse rating they call for) to deliver 15amps/110VAC. So that's 1800-2400watts of DC to produce 1600 watts of AC. So 66-88% efficient; ballpark 75% efficient... Compare that to the modern efficient sine wave inverters and they are low 90% but they also draw power when nothing is pulling/they are idling(old inverters are 80%). Though this spins and is the same sine wave power as the power company makes, it has one HUGE drawback: HZ and voltage are dependent on a constant 12.6V input. Lower/raise the DC voltage and the HZ/AC voltage swing with it. Computers all have their own power inverters/supplies built in and modify the voltage and HZ to fit their needs. Most will have a huge 110-250v and 50-60hz swing they say they can work with.

[@jbj27406]

@@sixtyfiveford Thank you very much for that reply. That was exactly the information I was looking for. I knew there had to be loss in both systems due to mechanical energy costs in the one case and some kind of heat/semiconductor drain in the other. That was still a great innovation prior to inverters coming along, but just a bit thirsty on the twelve volt system. 90% efficiency in the new inverters is very impressive. I know most solar units that power AC needs in homes have huge inverters, but there will always be energy losses in generation and conversion of power. Great video. I love how you analyze situations and devices that the rest of us have to just scratch our heads over. Well done.

[@ronniepirtlejr2606]

For every 1 amp you draw on the 120 volt side, you will draw 10+ amps on the DC side. ( a little more than 10 A. because of efficiency loss) 600 watts 120V. X 5 A.= 600 Watt. Or.... 12V X 50 A. = 600 Watt Must have a big battery bank with super thick zero gauge wire to draw any serious Wattage!

The great thing about these is that they just sit there using no power until you need it, if you are using a power saw intermittently you don’t have a generator constantly running in the background driving you nuts !

@@sixtyfiveford Hey there! First of all, you rule! Been watching your videos for a very long time. Not only didn't you sell out and produce only shill videos, your videos are still very very educational, I practically learn something new everytime. Regarding your question about the frequency: in aviation, as one can imagine, saving weight is of utmost importance. By drastically increasing the frequency you can significally reduce the needed amperage for a given amount of power. As current is the primary burden for cables, you therefore can reduce the wire cross section for a given load without overheating the cable, thereby reducing the weight of the electrical system. That's the same effect that allows to build much more compact and light weight items such as lunch box sized welders (inverter vs. old school transformers), although the required technology is quite sophisticated and not as robust as simpler designs (AC mains rectification -> chopping -> pulse width modulation amongst others -> and so on) Enough tech gibberish - thanks again and give ginger a treat!

[@D2O2]

@@szolo1986 The 400hz AC standard in aviation is to reduce component size and therefore weight, for example transformer cores can be smaller since they need less stored energy. Generator pole count and gearbox size reduction is another advantage. Additionally, it is easier to rectify to DC as the period for rectified 3-phase 60hz is 2.78mS, for 3-phase 115v 400Hz it is 0.417mS, so a lot less capacitance is needed to bridge the peaks and it is easier to filter the 400Hz "noise" riding on top of the DC.

Those 2-3A ones are a few dollars for the 5V USB output design, so I'm sure looking around there are cheap modules for whatever CV you want set... buck converter most likely technically with making an additional low voltage cutoff maybe if can't be built in the module to boost convert maybe I'm thinking.

[@trxtech3010]

Wow this is cool! I have never seen sometime like this.

[@sixtyfiveford]

Neither had I. I guess it makes sense that it exists though. From research it looks to be the go to mobile power device from the 50's-80's

[@PeterWMeek]

My dad had a few war surplus Dynamometers (Die-nuh-MOM-et-ers) that converted 24vdc to 120v @400Hz. About the size of a 24 oz Foster's can.

[@lukefarmer5391]

Is each plug 180 out of phase so you could 220 possibly?

[@letttttttssssss_gooooooo]

What a cool, strange, ...thing. Thanks for sharing! Neat!

[@sixtyfiveford]

Thanks for watching!

[@sham1234567891]

Great stuff! Where can this be purchased? Why is it produced anymore?

[@sixtyfiveford]

They're still made but electronic inverters have essentially replaced them due to cost.

[@staind288]

That is a really cool machine. Can come in handy

[@jamest.5001]

Just put a start button on it! What's the efficiency of these, probably better around 30-50% , and looks like besides the starting electronics, it could be wired in series for 24v,

[@leclozo5004]

Super chanel , look like 220vac compatible using the 2 plug.

[@sixtyfiveford]

Maybe! I'll have to check.

[@imark7777777]

I saw one comment mentioned they had a 240 version so I suspect there's two windings that can be put out of phase

[@DAS-Videos]

Pretty cool. I didn't know such a thing existed.

Becareful around the capacitors your gonna get a really good shock

[@ByronLybbert]

What if you hooked one up to a car or truck with the alternator spinning 14.4 volts and what type load it handle

[@whitefreeman5798]

it would be nice to see someone use one like this to put a pulley on and see what it does running off of a water wheel

[@bobbybyom5748]

Check Marty T.

[@tylerw4593]

So this is basically a mechanical inverter? Pretty cool.

[@sixtyfiveford]

Yeah, pretty much.

[@tblbaby]

very cool super cheap thinger because you kinda fixidated it, cool video again

[@darylhudson777]

I wonder if the two 110 VAC outlets are separate also. So on left 12 VDC would feed left side 110 VAC outlet and another 12 VDC would feed right side 110 VAC outlet. Or could combine them. I had something similar years ago and do not remember what brand. Is that a Blue Heeler ? Love those dogs.

[@icekohl]

Send this to BigClive

[@AkornzStash]

on a service truck, this would be far better than a solid state power inverter.

[@twistedhillbilly6157]

What are the chances the 2 sides run out of sync with other? if so,, you might be able to get 240v AC... We had something similar in a machine shop to get 3 phase for the milling machines.. You should be able to test it by using a meter or wiggy across the 2 hots

[@sixtyfiveford]

The shaft running through the center of the entire thing is one piece. Along with that it looks like the AC generator is only a single unit. So 2 DC motors, one on each side and a single 120V wound AC generator in the center. I think is just runs two DC motors as the amps required are pushing 200amps and one set of brushes can't handle that.

[@twistedhillbilly6157]

@@sixtyfiveford One of these days, I'm gunna be right about something and everyone will be amazed.. Basically that thing is the original version of an inverter and still better.. A rotating motor /generator will always produce a better wave than any inverter can because it's real.. I have been working on a project that would be perfect for that thing and might be the final system to take my house completely off grid.. Now I'm going to be searching the web and auctions to find one... Since side A turns on when a load is sensed,, could side B kick in at a higher load.. I can see that being handy for things like a fridge or an air compressor. Both sides kick in to handle the start up surge.....

[@imark7777777]

That's what I was thinking as well I would almost bet that the two sides have separate AC windings and one comment said they had a 240v version.

Can you use one side and the other side run a battery charger for the battery?

[@stans5270]

Does anyone else notice the similarities between Mo working on this generator and Doc Brown working on his Flux Capacitor??? - 88MPH I kept wanting to see Mo's new hairdo.

[@JOEZEP54]

LOL

[@smokyatgroups]

I have a possibly silly question for you, since its a purely mechanical inverter. Do you know if its possible to feed in say 115V ac 60Hz into the output and get dc 12V out of the input? Say to use as a battery charger for example although an in efficient one.

[@tcapo514]

there is nothing better than staying in the garage all day in messing with shit 😎💨💨💨💩

[@sixtyfiveford]

You can say that again.

[@carolinabeacher1558]

connect a battery charger to it and charge the battery with it :) seriously though that is pretty cool, id like to have one for my truck connected to a couple deep cycle batteries and some solar to keep the batteries charged when the truck isnt running.

Good vidio love the dog

[@jussiketels151]

Amazing, this is exactly what they sell today as a green generator… it was existing a long time ago, funny.. the question is, how long it is working with two 12 volt batteries.. I do think that this will work good like the new green generators! So it must be possible to connect a sun panel on it, so it is green powered!!😅

[@sixtyfiveford]

It doesn't last very long. It is around 75-80% efficient at converting DC to AC power

I got one to replace a rusted out one in my work truck, it worked first couple tries, then just started clicking...any idea what's wrong?

[@sixtyfiveford]

I would check the contacts on the relay. The clicking is the relay activating but it may not be passing power.

[@egodeathplease]

Question is can you spin that thing up with a battery then plug a battery charger into it then power it off the charger n unhook the battery?

[@RightArmDeals]

Efficiency makes this impossible

Yeah, essentially. These were common in things like service trucks, fire trucks, ambulances, motorhomes etc. They predate the electronic inverters that are everywhere these days.

Befor there were solistate inverters there were ether inverters with a vibrator or for larger current draws to step DC voltage up or down at larger current draws motor generarator inverters were used- on the B 17 bombers most of the equipment was 240 volts DC - the batterys along with the tail generator and radial engines generators were all 24 volts DC - 4 motor generators boosted the 24 volts DC to the aircraft operating voltage to 240 vots DC - also the radio ran off 110 volts AC 400 Hz, a inverter generator powered the radio and radars- Up till after WW2 most rural homes did not have grid power - rural homes that did have electricity primarily used 6, 12, 24 or 32 volts DC - there was. A complete line of appliances sold in 32 volts DC in small towns equal to any appliance sold in citys that were 110 volts AC in a city - A TV or florescent lights in a born ran on 115 volts AC - so farms that had a 32 volt house with a large bank of batterys had to use a motor generator for a TV or barn flouresent lights -to change the 32 V DC to 115 V AC - There were also 6, 12, & 24 volt motor inverters that stept up to 115 V 60 Hz AC -
