Abstract :

A method for predicting the steady-state performance of a squirrel-cage induction motor using finite element models was described.The method was used in conjunction with the conventional equivalent circuit model for a three-phase induction motor. The method uses separate finite element models for the rotor and the stator consisting of one slot pitch and one phase band, respectively. The use of minimal models led to a fast execution time for the finite element analysis.The method is illustrated by comparing finite element model predictions of performance with test measurements made on a 4-pole, 4 kW induction motor which shows a very good correlation.
