PURPOSE:To generate torque extending over the whole circumference of a stator, and to improve efficiency by displacing the center of the distribution of magnetic flux generated in the stator from the center of the magnetic flux of a rotor. CONSTITUTION:The Ns and Ss of permanent magnets are disposed alternately to the cylindrical rotor 11. The stator 12 is arranged to the inside of the rotor 11. The stator 12 is constituted by arms 14 disposed radially from the center 13 and pole teeth 15 formed at the noses of the arms 14, and the noses of the arms 14 are combined where displaced from the center of the pole teeth 15. Exciting coils 16 are wound on the arms 14. That is, clearances among the rotor magnet 11 and the stator pole teeth 15 are kept constant, and the center of the stator pole teeth 15 and the center of the exciting coils 16 is displaced. |
