ABSTRACT:
Each tooth of a stator core has circumferential projections at an inner tooth edge and circumferential notches at a base portion adjacent to a core back. A width of the teeth at the base portion is larger than a width of the same at the tooth edge. Therefore, the magnetic reluctance of the teeth does not increase. In addition, a plurality of the magnetic strips can be formed from a long and thin magnetic sheet. This increases the yield percentage of the magnetic strip and reduces a manpower of manufacturing the magnetic strip. Further, the notches make it easy to wind the magnetic strip into a cylindrical core.
