| Abstract |
The impedances in the induction motor (I/M) equivalent circuit provide a considerable amount of commutation impedance to the rectifier connected to wound-rotor terminals of the motor. This results in several tens of degrees of overlap angle in the rectifier. It has been reported that the overlap angle has a notable effect both upon the value of the average electromagnetic torque and prediction of torque neglecting the overlap is having an error of 15% [1]. This paper considers effects of overlap on the rectifier output voltage and also effects of the harmonics produced by the two converters present in the slip energy recovery system in calculating the electromagnetic torque of the machine. Pulsating torques arise from the interactions of all different harmonics. |
