| description | PROBLEM TO BE SOLVED: To provide a structure which can reduce the number of permanent magnets while securing desired motor torque. SOLUTION: An axial permanent magnet motor includes a rotor having a plurality of the permanent magnets disposed at predetermined intervals along the rotating direction of a rotary shaft so that poles are alternately disposed, and a magnetic element 24 disposed between the permanent magnets 20. Then, when a rotating magnetic field is generated in a stator disposed at a position opposed to the rotor, magnet torque is generated between teeth of the magnetized stator and the permanent magnet 20, and reluctance torque is generated between the teeth and the magnetic element 24. As a result, even if the number of the permanent magnet 20 is reduced and the magnet torque is reduced, it is compensated by the generation of the reluctance torque, and desired motor torque is secured.
