Abstract :
Schemes for drive and control of the traveling-wave ultrasonic motor (TRUM) is proposed in the paper and then the hardware circuit structure and the software designing of relevant functions for the driver is expounded in detail. The developed system includes two feedback loops; voltage control loop and resonant frequency tracking loop. Comparing to traditional driver of TRUM, this device has greatly improved the controllability of TRUM. Whatpsilas more, the motorpsilas velocity can be kept steady in different value.
