Abstract
PURPOSE:To smooth winding operations by forming main poles provided with windings of a stator part symmetrically in the direction of rotation of a rotor magnet. CONSTITUTION:A brushless motor is composed of a cylindrical rotor magnet 14 and a stator part having two main poles 11 provided with A-phase and B-phase windings, two main poles 12 provided with no windings and commutating poles 13. Said main poles 12 with no windings are provided with protrusion poles 11a-12a projecting only in the direction of rotation of the rotor magnet 14 so that they are formed asymmetrically with respect to a radial line. Therefore, when the main poles 12 is not excited, the pole center of said main poles 12 and that of said rotor magnet 14 deviate in the direction of rotation and the rotor magnet 14 stops at the position deviating in the direction of rotation. According to the rotational position of said magnet 14, power is applied to the winding of the main pole 11 provided with said winding and then switched to enable a continuous rotation of the rotor magnet 14.
