Abstract
A statoris provided with a plurality of magnetic poleson the outer circumference thereof, and is configured from a plurality of layers of plate-shaped members. A rotoris rotatably disposed around the stator. The inner circumferential face of the rotor is provided with a magnet. The outer circumferential ends of the magnetic poles of the stator are provided with an extended portion that is bent such that at least one plate-shaped member, including an outermost layer, of the plurality of plate-shaped members is substantially parallel to the magnet. When the inner diameter of a bent portion of a plate-shaped member that is the closest to the magnet of the at least one plate-shaped member constituting the extended portion is taken as R, and the thickness of the closest plate-shaped member is taken as T, R<Tis satisfied. Accordingly, it is possible to improve the driving efficiency of an outer rotor-type motor.
