The Experimental Research of Ultrasonic Motor in the Vacuum Environment

Chunsheng Zhao

Abstract

In order to study the effect of vacuum environment on the ultrasonic motor,it is necessary to carry out the vacuum environment experiment.By applying different pre-pressure,the speed,torque and temperature of the ultrasonic motor in low and high vacuum have been tested and compared with the normal condition.The experiment shows that the ultrasonic motors can operate in vacuum,but the performance is different from that in normal condition.
