Does anyone have any experience of running a large AC 4 pole induction motor at 100Hz this design has been offered to drive a pump with a 3000 rpm top speed < however the pump will normalyy run in the 2200 to 3000 speed range . The reason I was offered this solution was that the 2 pole motor originally offered was in reasonace at 1800 to 2600 rpm. A suitable 2 pole stiff rotor design does not appear to be available. We would be controlling the motor Via a Robicon VSD. Would we have torque issues above 50 Hz or can a motor be wound to reflect 100Hz as being its as manufactured top speed.
