Abstract | The invention relates to a microminiature stick-slip piezoelectric motor and a driving method thereof, belonging to the technical field of motors. The motor is composed of a piezoelectric stack, a rolling bearing, a bearing strut, a hinge mechanism and a base, wherein the hinge mechanism comprises a flexible driving plate, an auxiliary friction plate, an adjusting screw, a lever, a fixed end hinge, an input end hinge and a mounting hole. Friction force between the friction plate and the rolling bearing can be adjusted by adjusting the adjusting screw. The piezoelectric stack is electrified to extend and drives the bearing to rotate through a lever type flexible hinge, and directional driving of a sliding block is achieved through the friction force. The stick-slip type piezoelectric motor has the advantages that the stick-slip type piezoelectric motor is small in size and large in working area ratio by designing a compact structure; and meanwhile, the phenomenon of serious rollback occurring after miniaturiza |
