Abstract: This paper deals with characteristics evaluations for PM magnetization with a stator coil in a post-assembly Line Start Permanent Magnet Motor (LSPMM), using a coupled Finite Element Method (FEM) and Preisach modeling. The focus of this paper is characteristics analysis, relative to magnetizing direction and the quantity of permanent magnets due to eddy currents which occurr in the rotor bar during post-assembly magnetization and which effect Nd-Fe-B magnets.

Keywords: Permanent magnets, FEM, preisach modeling, LSPMM, stator coil magnetization
