My problem is that I want 415V 3ph power for my lathe which is a 3.75/7.5Hp constant torque 2 speed motor.
I have tried using a 3ph motor as a rotary convertor but as I have only single phase 240V going to the motor I cannot get enough volts out without the use of a big step-up transformer.
As I understand it I can use an 3 ph induction motor as a generator.
My Idea was to use either a electric or petrol motor to turn the 3ph motor used as a generator.
Would this idea work and how much drive power would be needed to drive the generator?
Would a 3Hp 2800RPM single phase motor be enough power to drive a 10Hp 1440RPM generator if it was geared at 1:2?
Cheers Andy.
