A Micro Piezoelectric Motor with a Disk-Pivot Structure

摘要：

　　A micro piezoelectric motor with a disk-pivot structure is presented.Different from conventional wobble-type piezoelectric motor using piezoelectric rod or cylinder,piezoelectric disc is used to excite wobble modes and metal cylinder stator is used to amplify the transverse displacement,metal rod rotor is actuated to rotate.The outer diameter of the actuator is 14mm.In this paper,the performances of the motor are characterized,where a high rotation speed and a high toque are obtained.The property of start-up period movement of the motor was studied by a high-speed camera.The toque of the motor was calculated by the property of the start-up movement.
