PURPOSE:To enable to increase the density of magnetic flux for the titled motor even when void length is increased by a method wherein a permanent magnet is installed on a stator and it is formed into a heteropolar type structure which allows to pass the magnetic flux in radial direction. CONSTITUTION:A plate-type ferrite magnet 32 is lined on the inner surface of a combined outer frame and yoke consisting of a soft steel plate, and a pole piece 33 is installed on the inside of the above. A coil inserting groove and induction teeth, located on both sides of the groove, are provided on the pole piece 33 utilizing the space provided at the four corners of the magnetic piece. A polyphased coil 35 is wound in the coil inserting groove, and the magnet is magnetized in such a manner that the pole piece 33 located at the four corners constitute the four poles of N, S, N and S. A rotor 34 consists of a gear-shaped laminated core, and the inductor teeth of the stator are cut in accordance with the pitch of the teeth. |
