Abstract: The eddy current loss of rotor support of axial flux permanent magnet (AFPM) machine was analyzed, and the effect of several kinds of rotor bracket materials with different electrical conductivity on eddy current loss was studied. The strategy to suppress rotor eddy current loss by optimizing rotor bracket materials was proposed.Theoretical formulas were used to deduce the model loss, ANSYS Maxwell was used for finite element analysis (FEA) to obtain the eddy current loss of the rotor bracket. A prototype test was carried out to verify the effect of optimizing the rotor bracket material on suppressing the rotor eddy current loss. The results show that the optimization of the rotor bracket material can effectively suppress the eddy current loss on the rotor and reduce the temperature rise of the rotor. This study has positive significance for practical engineering applications.
