Abstract

This paper analyze the dynamic performance of inverter fed permanent magnet synchronous motors (PMSM) using damping and synchronizing torques. A numerical algorithm has been applied to predict the performance using overall nonlinear model of permanent magnet synchronous motor. A comprehensive set of results for the digital simulation of the steady state and dynamic performances for a motor with and without pulse-width modulation inverter is obtained. The voltage , direct and quadrature current, and torque waveforms atdifferent modes of operations are presented in a comparative form, illustrating the differences caused by introducing the inverter. The effects of frequency variation due to the use of inverter on motor dynamic performance , and the optimum range of frequency is also discussed.
