Research on the Driving Mechanism and Experiment a Novel Linear Ultrasonic Motor Based on In-Plane Modes
Abstract: A new type of linear ultrasonic motor based on the first longitudinal mode and the second bending mode was developed. This paper analyzed the operating principle of the motor and the dynamic properties of the stator using the finite element method, and described the formation process of elliptical motion in detail. The prototype was investigated by the experiment, the motor could reach a maximum speed of 120 mm/s, the maximum thrust of 2.5 N, the ratio of the thrust to weight of 14:1 and the maximum efficiency of 8% at the case of the driving frequency was 55 kHz, peak operation voltage was 400 V, and the pre-pressure was 24 N.
