Old mechanical inverter DC AC 

Eric Wasatonic Thanks :)

it produce square wave

It'll be square wave usefull if battery series connected upto 230 vdc, most simple inverter just need a motor and commutators

pure sine not sqare it is just like the grid just smaler

Yesssss

HDXFH Yes, if the batteries would be bigger would work better :)

rene kenshin Thanks for the comments to my videos :) This video and others, are only for vision and curiosity, they have no practicality use in the field of electricity.

rene kenshin The one in the video is 52 yrs old, it looks like it is running pretty good! I have a 1980's winco mechanical inverter 24vdc 1200 watts @120 VAC works great and has never had a problem, why would you think it uses vibrators? I always thought it was just a 24VDC motor turning an alternator.

Ken Barnett I'm not talking about the one in the video, I'm talking about another type of inverter used in the past.

rene kenshin I have no idea how it works, I've never ran it without the cover on, so if you say it uses vibrators it just might!

Car radios up through the 1950's used vibrators to step up voltage for the plate supply of the tubes. Earliest car radios used dry cells for plate voltage, just like early home radios.

Yes

green N.R.G The description of the motor is written below :)

thanks buddy.

Amigo, infelizmente, eu não falo Inglês, só posso fazer comentários com google tradutor :)

You can replicate this principle using small DC motor like 775 and car alternator.

fidel catsro The advantage of this inverter is that the sine wave is perfect, the only downside is the noise ..

Electric Experiments Roobert33 Not entirely right. One big selling point of the electronic inverters is the speed at which they kick in. When they act as a backup, your appliance will keep functioning continuously. A motor like this will take seconds to spin up giving your equipment the outage you have been presumably trying to avoid. Another problem lies in the efficiency. DC motors aren't exactly known for their efficiency and often require centrifugal air turbines to cool the motor for any respectable load. Couple the losses of the alternator side to that and any mall inverter beats that by a longshot.

maybe if the dc motor can be replaced by a pulse motor with heavy flywheel and the alternator is replaced by a permanent magnet magneto this system can be greatly efficient?

That would take the "steampunk" spirit away as the beauty of this thing is precisely the lack of modern electronics. If you allowed a BLDC controller, you might as well do a solid-state power conversion from the ground up. EDIT: To improve stability without ruining it with overly modern approaches, one could equip the primary motor with a centrifugal switch that would stabilize the speed and act as a crude governor.

Robert Szasz His inverter may have that freq issue, I have a Winco 24vdc 1200 watt 120vdc mechanical inverter and it works great, starts right up and I have never came across a frequency problem, but I also use a voltage regulator between the batteries and inverter, I used it for grid tie for 2 yrs without even a hiccup, it just works every time all of the time. Mine doesn't make even half the noise that inverter is putting out either, but mine is circa 1980's not early 60's and made for a wind turbine.

Ken Barnett I was thinking the easiest way to get this device to be more stable. If you don't mind wasting a bit of power self regulation can be done with a couple secondary windings a transistor, and a diode bridge

Actually mechanical inverters are much more stable and dependable than electronic inverters, the inverter he is demonstrating is over 50 yrs old! A voltage regulator between the battery and inverter is a more common setup, however he is demonstrating the inverter using a dimmer to increase and decrease the voltage from 24 vdc down to I'm guessing 12vdc because the output voltage is 240VAC to 120VAC ...

Ken Barnett I'd agree that they are more durable, but if you need precise voltage and frequency control solid state, or a solid state controller is the way to go. If you have plenty of spare power, and can spare the space and weight a fully electromechanical inverter with good stability can be built (giant flywheel, mechanical load feedback) but unless you need something that will survive an emp, solid state, or at least transistorized control is easier.

I don't know about this particular one, but someone made one using a dynamotor and a 3000rpm bldc motor (with separate power supply so frequency doesn't lower under load) it had a 2 pole dc motor commutator and a 2 phase slip ring motor commutator. In total: One brushed motor (dynamotor) aka (rotary transformer) One brushless dc motor (rotary inverter) And 8 carbon brushes (total) to maintain

I have a 24vdc 1200 watt 120 vdc "Winco Pure sine wave inverter" I use it for a step to get into my bed... The mechanism looks like one iron frame generator or motor, it is not a separate dc motor coupled to an ac generator, but that is what it actually does inside of a single housing, it is the size of a concrete block and weighs about 70 lbs., nothing digital about this thing, I might do a video with an ammeter hooked to the DC and a kill a watt meter on the AC side and open it up to show what is inside, not much to see, just a motor and an automotive style voltage regulator along with the power connects.

@quinten van ginderen: Yup! And a clever design, too. In fact, You have on one side of the rotor a normal commutator hooked up to the winding. And on the other side of the rotor there are two or three slip rings also hooked up to the windings 180 or 120° apart whether you need single or three phase AC. No need to couple two units as all are in one.

What?

@@felixbeutin8105 well me engine kinde of refuse to stop so I have faulty back chargeing 12si delco alternator who runs at slow speed so I kinde of have also faulty blinker relay ground sone where me engine cinde of runs in union with blinker relay so thats with key compleately off. So I was wondering culd I use only alternator as cinde of magneto circuet aperantly there is some how engine runing with out ignition coil positive . So all that rubbish made me thinking how to make normal alternator to magneto ignition ore make that thing act as some sort of motor on demand . I simply crosed lot problems with me alternator from failing voltage regulator up to fumeling with hv capacitors up to strange ground problems including suspiciuse blinker relay who for some strange reason acts as ignition . But mostly I end up with dead baterry . So is there any way to use capacitor banks instead baterry and send full alternator power to ignition coil? I have unusual problems ok and those kinde of problems do diferent effects like over chargeing baterrys ,dead baterrys some times they hold charge at cold conditions for days all kinde of crap I experiance with me alternator even electric motor and magnetic brakeing including self ignition wia ground for some reason. Some effects are great but some are anoying . So any one know here how to control that deam thing? Because I acidentaly have all those problems randomly . Can for some reason the alternators rotor ore regulator ore stationary winding be used as cinde of ignition system and why does this acure ? Only thing I have in me car us 4 pin gm ignition module ,positive linear dashboard regulator and some 3pin blinker relay that deam thing refuse to stop me car and for some reason it has bade tendency to self acelerate engine with out tuching that deam engine . So preaty much at this stage Im anoyed any bright electritians here who know what the hell that deam thing is doing and why exactly has blinker relay to do with alternator??? So I want to fry that deam engine with evry thing alternator got so was wondering how to not get shocked with ac and not fry me baterry well the old ac magnetos cold do that but in me case aperantly its litel diferent. So yeah have unusual problem here

Yasmine Peerkhan In practice, the batteries do turn the motor which in turn actuates an alternator to 24 volts and then it is transformed to 230 volts using a transformer.

bryan lawless It only does the job alternator.

+MrTyssi Não é possível, significa um movimento perpétuo ;)

+Electric Experiments Roobert33 Acreditei que era possível assim o equipamento poderia trabalhar por mais tempo. Muito obrigado,boa sorte.

Jaime Inostroza The dynamo input is 24 volts DC, 24 volts AC out. The DC does not work with the toroid (transformer).

A DC motor that shares the same shaft with an AC generator

Actually it is a factual inverter, since it "inverts" the DC power into AC, a transformer, transforms voltage and amperage, an inverter creates the Hertz at 50 or 60 to produce AC from a direct current that does not produce a sine.

I recall reading in early 70s some motor homes had these or you could get a mechanical dc motor driven 120v generator before electronic.

the loss is all heat, and I don't think this is too much hotter than a modern converter

@@tamtrinh174 you forgot the friction, modern mosfet inverter doesn't create friction and can convert over 90% efficiency

@@yoshiakihisha8496 friction -> heat

@@yoshiakihisha8496 modern one doesn't create physical friction, but there is electrical "friction", if you understand what I mean

And connect the earth ♥️​@@tamtrinh174and connect a little capacitor starting

Feyyaz Güroğlu Mechanical or electronic?

Yeah mechanical :)

Feyyaz Güroğlu Yes, about 60%

cyberlord64 Yes, it might also be possible, but you have to to experiment to find out..

That's exactly what I thought. It would work well for the bulbs, not so much for any motors though. It would also place serious wear on any contacts used to break the current flow. Since a converter is considered to be heavy-duty equipment, any commutators should be avoided, or at least well executed.

cyberlord64 I have an old book which describes how a rotary converter uses slip rings (AC side) connected to opposite commutator segments (DC side), which outputs a sine wave from a DC source, although the book describes how to use it the other way round, with the AC producing DC using a commutator . I want to try this using an old universal motor.

Nathan Dance Do you happen to remember the name of the book? i am still curious about this. My attempt using the method i posted in my earlier comment was borderline successful. (I used the commutator of a universal motor myself). Large sparks, high heat, even a little smoke etc... Though in the end i did get a fully square waveform, AND after passing the output through a transformer in reverse did manage to run an ac fan. But i cant imagine running such a setup for longer than a minute, not unless you want to burn down your house...

I think the knob control is a switch, either 12v dc or 24v dc

christophersalvato11 That would mean drawing over 500A from the car battery. I'm not really sure how that is supposed to work. A pretty large car battery may be able to power the heater for 10 minutes if you don't include power losses from the inverter and internal resistance of the battery.(Which would probably be too high to deliver 500A continously)

What I would suggest doing is using a gas powered water heater. The second option would be one that uses a low power(500w?) 12v element that heats the water while driving the car. Hope this helps.

The coil is a 230V 24V transformer

Ok. This machine in video is machine which type?

Yes :)

+Jeffrey314159 Yes, they are coupled together AC DC
