Abstract:
The rotor of the present invention is capable of improving magnetic characteristics, general versatility and ease of assembly. The rotor comprises: a rotor shaft; a ring-shaped rotor magnet being disposed coaxially with the rotor shaft; and a non-magnetic cover covering an outer circumference of the rotor magnet. The rotor magnet and the cover are integral-molded with molding resin in a state where an outer circumference of the cover is exposed and both end parts and an inner circumference of the rotor magnet are covered with the molding resin.
