The object of the present invention is to simplify the structure of a rotor supporting induction magnetic poles in a motor, and improve the strength. A motor includes a stator having first and second armatures to form a rotating magnetic field, an inner rotor having first and second permanent magnets, and an outer rotor (13) arranged between the stator and the inner rotor. The outer rotor (13) has a rotor body (31) which supports first and second induction magnetic poles (38L, 38R) made of a soft magnetic body such that they are embedded therein. A phase of the first induction magnetic pole (38L) is matched with a phase of the second induction magnetic pole (38R). The first and second induction magnetic poles are assembled to the rotor body (31) such that they are inserted into linear slits (31a) formed in the rotor body in the axis (L) direction. Because the first and second induction magnetic poles (38L, 38R) are aligned in the axis (L) direction, the outer rotor (13) has a simple structure and an increased strength, and also support and assembling of the first and second induction magnetic poles (38L, 38R) in the outer rotor (13) are facilitated. |
