Power equals torque times angular speed. You need to know the RPM of the motor. Divide by 60 to get RPS, multiply by 2pi and divide by 1kw to find the required torque. This is ideal - you then need to divide by the efficiency of the generator.

It depends on the speed and the design of the generator
That to the extent where the net losses is larger than the net gain

So no quantitative answer!

Hope this properly answers your question

According to known givens, substitute in these formulae:

Torque  = Power / angular frequency

angular frequency = round per minute (rpm)  x  (2 ?) / 60.

Electrical wise :

Power = Voltage x Current = V x I

Min power = Power x Total effeciency

total effeciency = (electrical x mechanical x .... ) effeciencies


Please revise a text book in electric machines for more details.

Good luck.
