摘　　要：论述了采用分割电极的压电陶瓷来测量环形行波式超声波电机定子的谐振频率及定子表面行波的原理，实验结果表明这种办法简单易行，为判断环形行波式超声波电机定子是否正常工作提供实验根据。A new method is proposed to detect resonance frequency and traveling wave on the stator surface of annular traveling wave ultrasonic motor,in which piezoelectric ceramic whose electrode is divided is utilized as sensor.The experiment shows that the method is simple and practicable to judge if the stator of annular traveling wave ultrasonic motor can work normally.
