Abstract： Previous ultrasonic motor driver based on non-intelligent chip is limited by its disadvantage of complex circuit and difficult phase-modulation. Aiming at this problem， the basic principle and characteristics of traveling wave type ultrasonic motor driver was introduced. According to the requirement of ultrasonic motor driven signal，a multi-function adjustable traveling wave type ultrasonic motor driver was designed based on BiCMOS advanced phase shift pulse width modulation（PWM） controller UCC3895. The relevant circuits and experiment waveforms were also provided. Experimental results verify the feasibility of design.
Key words： ultrasonic motor； driver； UCC3895； BiCMOS phase shift； pulse width modulation（PWM）
