Patent ID: 7420310

Claim:
A brushless motor, comprising: a stator core having a plurality of radially-extending poles with a wire wound therearound, a hole in a center thereof, and a plurality of notched parts on an inner circumferential surface adjacent to the hole; a rotor comprising a rotor frame having at least one magnet attached to an inner periphery of the rotor frame, and a shaft fixed to a center of the rotor frame, the at least one magnet being located opposite the stator core; two bearings rotatably supporting the shaft, a part of one of two bearing abutting the inner circumferential surface of the stator core; and a housing holding the bearings and said stator core and having a central cylindrical part that has a larger outside diameter than the hole in the center of the stator core, said housing having a plurality of projected parts located at an outer surface adjacent the stator core at positions corresponding to the notched parts of the stator core; wherein a part of one of the two bearings not abutting the inner circumferential surface of the stator core is held in the cylindrical part of the housing.
