Abstract
PURPOSE:To bring the shaft of a supersonic motor into free condition, by providing a broke releasing mechanism for releasing pressure contact between a stator and a rotor. CONSTITUTION:A yoke 14 having inner diameter section fittable rotatably to a shaft 12 through a bearing 16 is internally arranged with an exciting coil 18. An armature 24 is fixed through a leaf spring 22 to the radially outer circumferential side at the open face side of the coil, and a stator 2 is fixed integrally. A piezoelectric element 4 is applied onto the surface of the stator 2 at the side of the armature 24. A rotor 6 has inner diameter section fittable to the shaft 12 and resiliently contacted with the armature 24 energized in the direction of the rotor 6 through resiliency of a spring A28 arranged on the yoke 14. When the shaft 12 is unlocked, voltage is applied across the exciting coil 18 to produce magnetic force for attracting the armature 24 to the yoke 14 while resisting against resiliency of the spring A28. Consequently, pressure contact condition between the stator 2 and the rotor 6 is released.
