Hello everyone!
I have the following goodies:
The big motors are wired at 55kV and rated for 120 Vmax and 500 amps.
My question is if it is even possible to rectify the combined 1000 amps at 120 V and then step the dc voltage down to the 70 required for the eight smaller motors.
The power discrepancies are due to rated and peak maxima and bad supplier labeling. Also the coupling of the 2 big motors (hopefully generators) to spin at the 6600 rpm required to gen the 120 V is rather easy for the Mechanical engineer side of my life.
I should mention that the 8 motors and the ICE are for free so I need to use them. But I have to either pay for the 2 big motors and rectifying circuits or for the batteries. Batteries are more expensive by a factor of 7 excluding charging gear. Perhaps another option is to make my own higher voltage generator and use off the shelf rectifiers (1600 V 100 A units are on ebay for cheap cheap)
Can this be pulled off?
Thanks in advance.

I have the following goodies:
- 8 x 15 kW brushless motors
- 70 V max
- max continuous current = 300 A
- A 120+ kW Subaru internal combustion engine. Only weighs 115 kg (250 lbs)
- 2 times/of 50 kW brushless motors. Which also only weighs 12 kg combined (27 lbs)
- the mechanical coupling of combustion engine to 2 big motors
- Fuel for more than a half hour of operation.
- And perhaps rectification.
