概要

The accuracy of the efficiency simulation has significant impact on the electromagnetic development of the electrical machine (EM), especially in the application of the electrical vehicle which requires extremely high economic performance in the typical driving cycles. A validated model based on the combination of the JMAG-Designer and analytical post-processing tool was presented in this document, with the separated simulation results of copper DC losses, copper AC losses, iron losses, mechanical losses and PWM-harmonic losses, in which the copper DC losses and iron losses were calculated by JMAG-Designer. In general, the comparison of EM total losses and efficiency maps shows good fit between measurements and simulations.
