Electric Power Generator With AC Motor

Electric Power Generator

You mentioned that you could run a small electric power generator to run an AC motor and the motors mentioned were the Solectria AC55 motor and the Solectria AC24 motor. I'm a bit confused about how much power would be needed from a generator to power these AC motors?
Also, how would you change the power for what is needed for the motor and where could I find that?

Hi, Mary!
Tossing your question over to Dan Bentler...

He says:
You would need an alternator (3 phase) to drive these directly. It would have to have the same KW voltage current as the motor and probably more to allow for starting current of motor - I would guess by added 10 and maybe 20%. The load driven by motor has a torque demand and this is what controls the whole "chain" i.e. load motor and alternator. load torque only 50% of full load then motor delivers only 50% and demands only 50% from alternator which only demands 50% throttle on prime mover.
