- Guys check out this super cool old military generator, it produces around 5Amps at 24Volts.
I found out that it was made in Slovenia, probably a long time ago, not sure about the year but i think at least 30 years..
It was used in a shelter probably for some lights...
Please enjoy the video and let me know if there is anything you would like me to do with it.. - แนวปฏิบัติและการใช้ชีวิต

This was made to use with a transmitter receiver unit - just enough energy to contact base. That is why the voltage stops just above 24V so that the radio is not fried! For lighting it would be an oil lamp I'm afraid and nobody could keep the generator running for more than a few minutes. They were often used by units in the jungle where a gasoline generator would have been too noisy.
It becomes easier to crank because you have a non linear, constant power load attached to it. Your step down circuit works linearly up to 12V or whatever you set the dc-dc converter then it flattens out the power. This means that as you increase the rotation speed above what generates 12V, the amperage, and consequently the torque required to keep the unit running decrease linearly. Which can be clearly seen by the fact that at full output power it draws "only" 3 amps while at 12 volts or so it draws 5 amps which is what those bulbs are rated at. (P = ωτ)
Very beautiful object anyway.
This is new ...it is from 80 years and are made in Yugoslavia
It is for army radio RUP 20
Power normaly is 25-30w no mor from hand in long term use.
Also is another one for 12v
I also have a lot of model of som kind of thing form 1944 to 1990 model
The best is from PRC 320 radio small and nice.
Use it like it is !
Good luck!
One of the purposes of that mobile generator was to power mobile comunication stations at the field... and yeah you should keep it cause it's made to last forever and it's very good quality ...
This is a quality unit , no one could make such quality a unit in 2020.
The feed back circuit is to excite the armature. That means it doesn't have permanent magnets as an armature. It's a car alternator rectified to DC with the armature being self excited instead of excited externally by a battery. Once u fill up the capacitors it powers the armature and turns it into a high powered electromagnetic. Advantage over permanent magnets is it's more powerful and 1/10 the weight. It's a hand cranked car alternator. It's in great condition 👍
Great description, thanks for watching
I was going to say, it looks like its regulated to 24.6/24.5 volts. That's why it got easier for him to turn it once the voltage came up. That would be a neat generator to connect to a water wheel
If it does not have permanent magnets to create flux, then it mush have external battery energy to create a flux in order to get the whole thing going. Even alternators need external DC to get the field going before the stator can generate energy. So in order to fill up the capacitors, it must have some tiny magnets on the armature to get the excitation circuit to do it's job.
Great info!
Thanks for sharing this. I've seen them on war movies and it looks cool. Good for emergency.
Dame your lucky to have a dad that gives you power
i see this generator first time ... so thanks for sharing
Great presentation. Your English is excellent. I heard an accent but perfectly understandable but this old American.
Thank you
Very interesting, quality piece of equipment. Looks brand new inside. Great video, and your English is perfect, thank you for sharing this with us.
Very interesting, thanks for sharing bro.
That's really cool. If you don't restore it to original at least clear coat it to keep it in original condition.
Indeed a very nice information video thanks
Your English is very good.
Thank you :)
Nice piece of history
Very nice ! I too am 4 years late ! I would keep it original, historical piece
You can be sure it was built after 1958, since that year saw the first power transistor. So early 60s at earliest.
Your English is very good. Thanks for the video. Very interesting.
Excellent video and your English is excellent as well I would not have even noticed that you didn't know English until you told us.
Thank you, means alot!
Excellent video
Thanks
Nicely made unit in it's day. Gearbox sounds a bit loud but operable. This is why I made my own generator that would serve as an experiment for LOW RPM, such as 1 to 1.5 turns per second, 60 to 90 RPM with NO Gears or pulleys, Silent. My findings with hand crank devices are basically used for low power applications because the torque required to go more than a watt or so will become a task that you really don't want to do for sustained time frame. The end result is that it is an energy converting device that you don't want to sweat over too much when it comes to doing the physical work. You can see it in operation on my channel powering up an array of 900 LED's. I was able to generate around 8 to 10 or so watts, but it was work. Leg power can be better than using wrist for more energy.
Wow! The inside looks new...
Probably never opened
These where meant to charge the battery banks so the load would be minimal at the time of cranking. You would use at a steady pace about 1 crank a second for 30 minutes every few hours to recharge the batteries
Your English is better than some people I know and I am in an English speaking country.
Thanks you, means alot, boost in confidence also :)
ur English is on point bro! I know I'm 4 years late tho heh
it would be more interesting if it were applied to a gravitation system: a clock that by letting a weight go down, for 10 minutes, recharges the battery. Anyway congratulations.
I would think they would have made it so it would run much quieter than it does so enemy’s wouldn’t hear it. It could probably be heard a mile away, it’s very loud. Really cool I would like to find one.
I used hand cranks when I was in the British Military. This looks like a NATO specced piece of kit (24V was standard across NATO), the connector looks very familiar. We always used them to charge NiCad batteries for a HF radio. It was impossible to transmit using just the hand crank but you could receive.
Make a giant portable power bank using super capacitors. I saw another video where a guy made a boost box and was able to jump start a car and run a circular saw.
Your english is very good.
wich doesn't work. At least not for long. This thing makes barely 70W for a few seconds, a saw needs 2000W to run. So this will be a short fun.
This was actually probably for radio communications, radio was a crucial part of WWII and you need power for radio no way around it. 24 volts could charge up a flat vehicle battery too, lights was probably just a bonus over various types of fuel lighting
That was built after WWII and is to NATO specifications. I would say 70's myself.
Would love to have one of these, or something similar....
Quite a workout
Your English is good enough. Good vid
Thank you
So it's a 120 watt 24vdc battery charger, that's very handy in the bush. Charges 2 car batteries at the same time. 24 vdc makes an excellent dc welder in the bush. Nice find brother. Batteries were usually 6 vdc back then as well.
First of all, you will need 14.4V to charge the car battery and second, why you need dc welder in the bush :D
@@banny123456 to weld up trees?🙄
holy crap , 3-4 amps. that is begging to bolt onto an exercise bike.
That Was To Power Short Wave Transceiver
Your English Is Fine
Yes I Think It Would Be Good To Re - Paint It
Bless Up Earthling
set up in a recumbent bike set up and enjoy the ride and get strong legs
Was wondering what kind of engine it had. Seems to run on borscht.
one more its called a Gibson girl as per my experience in the army corps of engners
Прикольный акцент 😉
Just cleaned up
Fine
The printed circuit board is fiberglass. They did not have fiberglass circuit boards during the War. If the printed circuit board is original, then this cannot be a WWII Generator. In fact, it is unlikely there would be a circuit board in it and everything would be hardwired. Plus those resistors did not come from that era.
How can I purchase one of those?
Just Asking, is that possible to charging the handphone?
Yes, you can charge almost anything, you just need a step down regulator to adjust the voltage you need for charging and regulate the charging current :)
i want one
that circuitry looks younger than 1960.
It looks like a circuit board made of fiberglass used in a 70's large company design computer i got from dads work back in the 90's.
Also the resistors is different and more modern than my old radio from 1950 and 45.
I got a radio from 1958 too, and the color of this pcb is medium brown and not fiberglass print card board.
So yes, agree, way more new than the war, at least the war we think about :)
But perhaps he ment the Vietnam war? I bet it is from 1967 and up.
I ment the war my country was in, in 1991 to 1995
DIY Garage Projects and reviews just curious if you restored it
Where did you get it from ??
As he said in the beginning of the video, from his father.
your English is gut
What is the OUTPUT voltage is it in AC or DC pro-bably it is AC and so , it would be EASY to trans-formed the VOLTAGE to > HIGHER voltage for VAcuum tube PLATE supply the B.
If you watch the video you can see that it it a dc 24.5v output
@@DIYGarageProjects I like your GENERATOR but it is NOT avai-lable here at Philippines. It is GOOD to power RECEIVER during TY-hoon I need that for EMERGENCY pur=poses es=pecially here at Philippines there are a lots of DISASTERs and Calamities ,Thanks for INFO .
is that a Yugoslavia language on the door ?
Yes
its a time machine 12:30
Такое ощущение, что твой родной язык русский.
DO NOT REFUBISH IT, it's worth far more un-painted.
inside, that's an alternator, NOT A GENERATOR, it's not nearly as old as you think, Jim David, master auto mechanic alternators were invented in 1970 or thereabouts.
yeah, this is probably not old than 50y. Electric cable and rubber seal are in relatively good shape. WW2 rubber will no survive until now.
@@banny123456 yeah, I also thought from the beginning this is more like cold war era. So late 70s or 80s.
A house needs 30 kilowatts to power it a day
Thats is so far from reality, and it doesnt make sense
To bad it real man or woman lol
I have 1944 us army hand generator burke electric.co
