[L-SE-59] Detailed Modeling for Higher Harmonic Loss Analysis

Overview

In IPM motors driven by PWM inverters, eddy current losses occur due to carrier higher harmonics. For higher efficiency, it is important to evaluate higher harmonic loss at design time. In order to accurately obtain the higher harmonic loss, it is necessary to generate an optimum mesh for the evaluation of the loss. In JMAG it is possible to automatically perform mesh division optimally for each part. In particular, it is possible to generate meshes for complicated geometries such as for around the coil ends of a motor or for a skew.
In this demo, the fact that it is easy to perform analysis from modeling the details of coils and magnets based on evaluating eddy current losses generated by PWM driven IPM motor coils and magnets is introduced. The model to be evaluated is an IPM motor with 4 poles and 24 slots. There is a step skew in the rotor, and it is assumed that it is driven by a PWM inverter with a carrier frequency of 10 kHz.
