Drive Characteristics of Ultrasonic Motor under Vacuum and Low Temperature——No-load Characteristics
真空低温环境下超声马达驱动特性研究― 空载特性

The no-load speed of ultrasonic motor(USM) with different friction materials of four selected engineering plastics was measured by using testing system of friction drive characteristics of USM under vacuum and low temperature.The effects of vacuum degree,environmental temperature and friction materials on no-load properties of traveling wave ultrasonic motor were researched.The results show that the no-load speed of ultrasonic motor decreased with the increase of vacuum degree and decrease of environmental ...
