A motor including: 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; and a stator for generating a field for driving the rotor. The permanent
magnet type rotor unit and the reluctance type rotor unit are given an angle 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 angle 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.
