This paper presents a complete model & process for predicting the iron losses in electric machines. The method includes material measurement, data fitting for loss coefficient determination, FE computation and experimental validation. The model is based on the loss separation of hysteresis and eddy-current losses. Also a least squares based method of curve fitting, to obtain material loss coefficients for FE analysis, is derived from the tested specific core losses of a steel lamination ring sample. The generality of the completed method is further verified b application to different steel types and electric machines. The results predicted by the model show excellent agreement with the tested data for a high speed PM DC motor and a PM BLDC motor.
