Experimental Research on Revolving Travelling Wave Ultrasonic Motor

Introducing a kind of the revolving traveling wave ultrasonic motor.Besides,discussing the operation principle of the traveling wave in oscillation mechanics.Using ANSYS FEM software,analyze the influence to the eigenfrequency of the stator in different dimension parameters of the stator.The measuring PZT has been adhered to either side of the stator,measuring voltage changes of it making use of piezoelectric effect when the ultrasonic motor works.Furthermore,analyzes the characteristics of the ultrasonic motor in the resonant state.
