Investigation of loss, torque ripple and tooth forces of an ASM with sinusoidal and PWM feeding

Abstract

Abstract This thesis compares the performance of induction motor when supplied with purely si nusoidal input and PWM on with focus on the motor characteristics such as tooth forces, torque ripple and losses. A minimum loss control algorithm is employed based on the in verse gamma model of IM where core losses are modelled as the losses in the equivalent core resistance.The IM was modelled in Finite Element Method (FEM) software called ANSYS Maxwell.
