ABSTRACT:
A motor has a stator and a rotor that is formed of two rotor parts fitted on a rotor shaft in a fashion preventing the rotor from rotating relative to the rotor shaft. The rotor parts carry permanent magnets arranged with a fixed pitch angle over their outer peripheral faces. The rotor shaft has a single key for engaging with both an engagement groove of the first rotor and an engagement groove of the second rotor. The engagement groove of each steel plate forming the rotor parts is formed in a position shifted 1/2 of the skew angle from the pole center of a given one of the permanent magnets. The steel plates of the first rotor part and the steel plates of the second rotor part face in opposite directions when fitted to the key of the rotor shaft, thereby providing the predetermined skew angle between the two rotor parts.
