This paper deals with the post-assembly magnetization process of motors using ferrite
permanent magnets. In order to meet the needs of mass production, most motors are magnetized
post-assembly. However, increasingly complex shapes are required to maximize the flux of
permanent magnets. As a result, certain locations in the magnet are not fully magnetized by the
magnetizing fixture due to insufficient magnetomotive force. Therefore, an analysis concerning
the post-assembly magnetization is needed. In this paper, the concentrated flux spoke type
synchronous motor is analyzed to magnetization process, and then the magnetization level is
compared by linkage flux value between post-assembly and fully magnetization. Finally, back
electromotive force is estimated by post-assembly magnetization method the according to the
magnet shape.
