An accurate iron loss estimation method has been required for designing high-efficiency rotating machines for the vehicle.
One of the issue of the iron loss estimation is considering time harmonic and space harmonic. As a method of modeling physical phenomena such as minor hysteresis loop caused by harmonics and skin effect of eddy current in laminated iron core, after the two-dimensional magnetic field analysis, as postprocessing, a hysteresis model and one-dimensional magnetic field analysis is available.
In this presentation, we report on the accuracy when the iron loss estimation model using hysteresys model to the single sheet and the motor, and the problems clarified in the application.
