Your talking about a motor generator, a RPC uses a 3Ø motor to manufacture a phase from a single phase supply to operate 3Ø motors on a 1Ø supply.
You are right, my bad. We did use a MG
At a former employer we had a 100 HP MG set for 400HZ power, it was a PITA to cool the room where the transformer & MG set was, it was later replaced w/ a inverter....
