Abstract

PURPOSE:To stabilize braking characteristic by relatively moving yokes, the magnetic pole portions of which are opposed to an exciting coil axially fixed and an armature with a permanent magnet in the axial direction. CONSTITUTION:An armature 1 is secured to a shaft to be damped, which causes the armature to be axially immovable, and yokes 2, 3 to be axially movable together with permanent magnetic flux 6 to the armature 1 and the exciting coil 7. Therefore, in process of gradual decrease of magnetic flux phi2 generated by the exciting coil 7, a brake is released before the magnetic flux phi2 is equal to the magnetic flux phi1 by the permanent magnetic flux 6. As a result, the range of exciting current value by the exciting coil for making a braking torque naught can be expanded so as to stabilize releasing characteristic.
