Something strange: M1123 HMMWV 30kw On Board Generator Equipped Prototype 6.5L 4-speed

[Guyfang]

Info on this strange setup.. Unit is equipped with a 30kw 3-phase generator sandwiched between the 6.5L diesel engine and the 4-speed automatic transmission. This is believed to be one of two prototypes that were made. The generator is designed to feed a rectifier behind the passenger seat, which in turn fed a 3-phase invertor behind the drivers seat so the appropriate AC voltage could be produced regardless of engine speed. Currently the generator produces 3-phase AC power, but the invertor appears to be non-functional. The engine is equipped with a electronic governor, so the truck can produce AC power in at 220V for house hold applications, or 208V 3-phase as required.

I asked someone in CECOM about this "thing". His reply was:

They made 2 models. Both revoked. In 2004 they started from TACOM something called a Viper. TACOM stopped almost immediately but the firm continued even after they sent out a sound because of several burn ups. Something about 400 vac and not insulated well. The second attempt was halted because of the HMMWVs going away
