Abstract The objective of this paper is to study the stick-slip distribution of the contact area between stator and rotor in traveling wave ultrasonic motor taking into account the shearing deformation of the frictional layer. Firstly, the tangential stress is calculated assuming that there exists only stick distribution in the contact area. Secondly, the tangential stress is compared with the sliding frictional stress. The stick-slip distribution as well as the performance of the motor is determined then. Finally, the analyzed result is verified by the experiment, and good agreement is obtained. The result is identified as being useful in designing and analyzing the ultrasonic motor.

Key words： Ultrasonic motor stator and rotor contact area stick-slip distribution
