Abstract

The effects of saturation on the terminal conditions of an induction motor are examined to provide information on the flux in the machine. A signal is extracted from the observed nonideal waveforms to allow tuning of the model used by the motor controller. This general principle is tested in one special case. A scalar controller, incorporating a form of phase current sensing utilizing the DC link fault current transducer, is known to be sensitive to thermal variation of the stator winding resistance. The phase angle of the point of the motor is chosen as the nonideal property on which tuning of the resistance parameter for thermal variation is based. The insulated gate bipolar transistor controller is implemented and tested with an inverter and a 500-W cage induction motor.
