PURPOSE:To enhance the utility rate of a space and to reduce the size and weight of a brushless motor by winding an armature winding and a detector winding in multi-division slots of a stator, and securing a permanent magnet to a recess formed on the pole of a rotor. CONSTITUTION:A stator core 111 and a rotor 12 are formed in a rectangular shape in section as seen from the axial direction, and E-shaped magnetic paths of the core 111 and the rotor 12 are spaced oppositely through an air gap 13. An armature winding 112 and a detector winding 113 are mounted in the multi- division slots of the axial direction of the rotational shaft of the core 11. The rotor 12 is formed in the irregular shape in the axial direction of the rotational shaft at the pole 121, and a permanent magnet 121 is secured to the recess. |
