A Methodology to Simulate Induction Motor Dynamic Performance in the ABC Reference Frame Considering Mixed Eccentricity Effects

Abstract

This paper presents a methodology to compute the inductances of the abc induction motor model considering mixedeccentricity. The winding function method (WFM) is employed to calculate the magnetizing inductances. Moreover,the air gap is approximated by an expression which can consider the case mentioned before as well as the healthycase (i.e., with uniform air gap). Due to the fact that the dynamic performance of the machine depends strongly on itsinductances, some basic dimensions of a real machine are used and a comparison between different free accelerationcharacteristics is given such as currents, electromagnetic torque and speed.
