ABSTRACT:
A motor includes a rotor including a permanent magnet type rotor unit having a plurality of permanent magnets and a reluctance type rotor unit having a plurality of salient pole portions, the rotor units being coupled to each other in an axial direction. A stator generates a field for driving the rotor. The permanent magnet type rotor unit and the reluctance type rotor unit have an angular deviation therebetween in the direction of rotation to obtain desired torque characteristics. The reluctance type rotor unit has slits for preventing flux leakage from the permanent magnets. The slits are formed with the angular deviation in the direction of rotation from respective positions symmetric about a center of the salient pole portions. Flux leakage is thus prevented to avoid deterioration in characteristics.
