Structure Design, Dynamic Simulation and Characteristic Measurement of a Thin-Disc Ultrasonic Actuator

摘要

In this study, we constitute and propagate a three-phase reflected wave based on the purpose locations of constraints. The wave configuration could convert electrical energy to actuate the kinematical power for rotating the rotor. Moreover, in mechanical design, the benefits of this novel ultrasonic actuator are the separated design in both of rotors and stators, convenient arrangement in mechanism, manufacturing cost in cheap and simple structures in thin. Since the high rotary speed is closed to 3500 rpm, the motor keeps the potential and developed commercialization in future.
