I saw this on e-bay and just had to share it. If I had the room (and a couple extra bucks)I would be tempted to buy it just to play with.

Almost think you could get 2 gennys out of this.

phase converter, big deal.

First off I want to say the link worked. Obviously this device uses a motor running off 60hz and converts it to aviation electrical standards for frequency, most likely different than 60hz. I once found some 60hz to- 415hz converters, The cabinets were sweet. I saved one, it took a fork lift to remove the gen-motor-set from the cabinet, I figure it will make an excellent batt storage cabinet. Could easily hold 60 or so auto-style 12v batts.

Had a quick look at this but there seems to be very little (i.e. none?) information about the output etc. of the generator. Don't know how old it is but a lot of early aircraft used motor driven generators such as this to provide the HT voltages for on board valve equipment. I would want to know more details before I considered buying something like this.

Military aircraft of WWII used 400 cycle(hertz) elecronics . All equipment was 24volt 400 cycle.MotorGens very common then.Our Ground Power Units for starting Fighter aircraft were 24 volt 400 cycle also. Last time I saw one was  at Buckley Airfield outside Denver Colorado in 1960 when I was a fighter plane mechanic, Some early jet fighters also used the 400 cycle power supplies. Don't know if the 24 volt 400 Hz still being used tho.

I knew that someone would know about this. So as I see it this was probably just used as a bench power supply for the older aviation electronic devices. 400hz ac 24 volt. That is an interesting little tidbit. I never would have guessed. Thanks.

Current Aveation power is 1600 Hz, not sure of the voltages

The electric supply in modern jetliners is 120VAC 400Hz. Thats for the onboard electronics like coffee maker etc. Don't know about the starters.
