Rotor of motor, method of producing the rotor, inner rotor-type brushless motor and method of producing the motor

摘要

The rotor (2) of the present invention is capable of improving magnetic characteristics, general versatility and ease of assembly. The rotor (2) comprises: a rotor shaft (1); a ring-shaped rotor magnet (3) being disposed coaxially with the rotor shaft (1); and a non-magnetic cover (4) covering an outer circumference of the rotor magnet (3). The rotor magnet (3) and the cover (4) are integral-molded with molding resin (5) in a state where an outer circumference of the cover (4) is exposed and both end parts and an inner circumference of the rotor magnet (3) are covered with the molding resin (5).
