A Performance Model of an Induction Motor for Transient Simulation With a PWM Drive

摘要

The goal of this paper is a method for the simulation of an induction motor driven with a pulse width modulation (PWM) three-phase bridge. The approach taken here decouples the circuit simulation from the electromagnetic field simulation by first constructing a performance model of the machine using 2D finite element (FE) analysis. The model consists of the complete matrix of the self- and mutual inductances of the stator windings and each of the rotor bars. Skew is taken into account by a correction applied to the winding-bar inductance entries in the matrix.
