Abstract:
A motor and stator include first and second laminations arranged adjacently in the axial direction. The laminations include sub-yoke parts and first tooth parts. The sub-yoke parts are spliced through a yoke engaging part to form a substantially annular yoke part. The tooth parts are assembled on an inner edge of the yoke part through a tooth engaging part. A first tooth engaging part and a second tooth engaging part are superposed in the axial direction, the first tooth engaging part being different from the second tooth engaging part. A method of manufacturing a stator for a motor is also disclosed.
