Abstract

In this paper, we investigate the eddy current losses in permanent magnets in a surface mounted magnet synchronous machines. A 2D analytical method is presented to calculate the losses due to the time and space harmonics. The validation of the analytical model is led through a 3D finite element method. The proposed method is then applied in case of a generator charging a battery through a full-wave bridge rectifier.
