发明名称 High torque ultrasonic motor system
摘要 The present invention is a compact, low mass, and low power consumption piezoelectric ultrasonic motor with high torque. The piezoelectric ultrasonic motor of the present invention includes a polarized piezoelectric drive ring or wafer comprised of a plurality of arc piece piezoelectric elements. The piezoelectric ultrasonic motor can utilize one or a plurality of piezoelectric wafers stacked as layers to increase the torque of the motor. Also, a series of the piezoelectric motors can be stacked and operated synchronously, as one motor, to maximize the torque within the volume, mass and power specification limitations of a specific application.
