PURPOSE:To reduce a cogging torque by employing a stator core having salient poles opposed to the peripheral surface of a magnet rotor and winding leg pieces at both sides, and winding coils on the leg pieces, thereby increasing magnetic fluxes. CONSTITUTION:A rotor 5 is composed by coaxially bonding a 2-pole permanent magnet rotor 5a and a 4-pole permanent magnet rotor 5b, and passing fixedly a shaft 6 through the center. Stator cores 7a, 7b are formed substantially in U shape with a salient pole 8a having a circular arc opposed to the periphery of the rotor 5 in the flat shape of thin plate core pieces, and a pair of winding leg pieces 8b, 8b extending from both sides of the pole 8a. Coils 9a, 9b are wound on the leg pieces 8b, 8c. |
