Abstract :
This paper presents the results of simulation of an interior permanent magnet synchronous machine (IPMSM) modeled using different magnetic characteristics. In each case the same steel is used and comparisons are made between manufacturer´s data and two sets of Epstein test data. The two Epstein data tests are for material with and without stress relief annealing (SRA) treatments and include characterization of the magnetization curves and loss over a wide frequency range. Using finite element analysis (FEA) the performance of the machine while operated under identical control conditions is evaluated. Torque, power, voltage and inductance values are compared.
