PROBLEM TO BE SOLVED: To provide a rotor, that brings about damper effects in a permanent- magnet motor and is of a simple structure. SOLUTION: One or more permanent magnets per pole are installed inside a laminated rotor core, and a stator core has single-phase or three-phase multipolar slots; single-phase or three-phase armature winding is wound in the slots, to form a permanent-magnet motor; and the permanent-magnet motor is so constituted that a single short-circuit ring is placed around a permanent magnet group of one pole.
