AbstractWith the advantages of lightweight, compact size, fast response, power-off holding torque and high-torque low-speed characteristics, the traveling-wave ultrasonic motor (TUSM) is becoming attractive for servo application. This paper presents a new pulse width modulation (PWM) method for servo speed control of a TUSM. The key is to digitally control the pulse width, hence the fundamental value, of the bipolar 2-phase voltages feeding into the TUSM. This method takes a definite advantage of minimum audible noise compared with those available methods, such as phase-difference control, frequency control, and on-off PWM control. Experimental results confirm that the proposed speed controller can offer good steady-state and transient performances and can significantly suppress the audible noise occurred at speed variations.
