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