A methodology to simulate induction motor dynamic performance in the ABC reference frame considering mixed eccentricity effects

This paper presents a methodology to compute the inductances of the abc induction motor model considering mixed eccentricity. 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 healthy case (i.e., with uniform air gap). Due to the fact that the dynamic performance of the machine depends strongly on its inductances, some basic dimensions of a real machine are used and a comparison between different free acceleration characteristics is given such as currents, electromagnetic torque and speed.
