Abstract
In permanent magnet synchronous motor (PMSM) drives the current ripples due to the pulse width modulation (PWM) applied to the phase voltages, can lead to undesirable effects on the torque. The aim of this paper is to present an analytical model which gives a quantitative analysis of the current and torque ripple induced by the PWM in PMSM electrical drives. The model based on a two time scale approach is presented by considering a two phase machine and it is shown that its extension to the three phase machine is straightforward.
