Abstract
The behaviour of a 9-phase squirrel cage induction motor is studied when it is excited with unmodulated and chopper modulated quasi-square phase voltages. A 9-phase bridge inverter, which produces the quasi-square waveforms, and its digital controller have been constructed and tested. A theoretical analysis is included, which shows the influence of phase current harmonics upon output torque.
