Document Type and Number:
Japanese Patent JP4679374
Kind Code:
B2
Abstract:
A motor includes a motor case having an opening part and a stator core disposed in an inside of the motor case. The motor case may include a bottom face part, sidewall parts extended on the opening part side from an outer periphery of the bottom face part, and cutout parts formed by cutting the sidewall parts. Non-contact parts are formed in an outer peripheral edge of the stator core so that the stator core does not contact with an inner face of the motor case at the non-contact parts, i.e., with a burr formed at the cutout part of the motor case. Alternatively, the motor case may be formed as an outer stator core and the stator core may be formed as an inner stator core.
