摘要：

The life of ultrasonic motors is limited by the wear of friction materials used for the contact surfaces, In order to reduce the wear of the function material, we hats to reduce the sliding speed between the sliding surfaces of the motel. In this report, we propose a new driving method to reduce the sliding speed of the motor by shaping the vibration speed waveform . The sliding loss was calculated and wear reduction effect was confirmed. A wear test was carried out under no-load condition, This method prolongs the life of an ultrasonic motor by about 3.4-fold. The results and wear reduction effects are also described.
