Abstract

This paper presents a method for calculating the eddy current loss in a permanent magnet (PM) of a surface PM (SPM) motor based on a reluctance network analysis (RNA). First, an RNA model of the SPM motor that accounts for the rotor rotation is described. Then, the eddy current loss in the magnet of the SPM motor including the carrier harmonics is calculated by the proposed model. Finally, it is demonstrated that the RNA model can consider the effect of the division of the magnet to reduce the eddy current loss in the magnet.
