Abstract

This paper presents the predicted performance of an interior permanent magnet synchronous machine (IPMSM) operating in wide speed range. The predictions are carried out with material properties obtained using from Epstein tests on samples that have undergone different treatments together with stress released annealing. Results of the Epstein frame tests for permeability and core loss density are presented, together with hysteresis B-H curves. Finite element analysis is used to investigate the variation of torque, power, saliency ratio, and core losses, after the different heat treatments have been applied.
