【Abstract】 Based on the mode analysis of the stator of a ultrasonic motor using in plane bending vibration, three kinds of in plane vibration modes are obtained, and the influence of the motors structural parameters on its modal frequencies are discussed. Some helpful conclusions are given, which provide theoretical basis for the design of this type of motor.更多还原
