Actualy what he says is true.You can drive a 3ph mtr with a single phase mtr and it will generate 3ph. You can run a 3 ph mtr on single phase by powering it on two legs and turning the mtr by hand to start it if you read voltage on the third leg and the other two you will see you have 3 ph. It dose work I have done it .Problem!!! It is not cheap power. Any 3 ph mtr with brushes is just a 3ph generator when driven be it by single phase or a gas engine.
