FLAT TYPE BRUSHLESS MOTOR

摘要

PURPOSE:To shorten the axial length of a motor and restrain the total height of an equipment by a method wherein one part of a stator is notched and a motor pulley is provided between a driving magnet and a back yoke while one part of the running system of the equipment is constituted in the main body of the motor. CONSTITUTION:A motor pulley 2a is formed at the center of a rotor boss 2 and is provided between a driving magnet 3 and a back yoke 5. A stator 9, retaining a predetermined gap between the driving magnet 3 and the back yoke 5, is arranged so as to have a conduction zone which corresponds to an electrical angle of 120 deg.. The stator 9 is fixed to a bracket 10 made of a magnetic material and one part thereof is notched radially from the inner diameter toward the outer periphery thereof to position a belt 11, applied on the pulley 2a, in a notch 9a.
