Abstract
PURPOSE: To prevent the increase of cocking even if ambient temperature rose by the procedure in which permanent magnet for braking is fixedly provided and then the permanent magnet is arranged face to face with the magnetic pole side of rotor.
CONSTITUTION: The bimetal 10 is provided on the outside cover 9, and then the permanent magnet 12 for braking is provided on the bimetal face to face with the magnetic pole side 11 of rotor. In the permanent magnet 12 for braking, the same polar magnetic pole tooth 13 is formed in the face of the magnetic pole side 11, and also each of the magnetic pole tooths 13 is in the face of the same or different pole. Thus, when ambient temperature rises and the bimetal is expanded, the braking permanent magnet 12 comes near the magnetic pole side 11 to prevent the increase of cocking because of its braking effect even if the thrust wearring loss torque is reduced due to the rise of ambient temperature.
