Abstract:
The comprehension of ultrasonic motor performances as a function of input parameters is a key to intelligent motion control of motor. This paper presents a performance estimation model of a novel rotary ultrasonic motor as a function of input parameters. To evaluate performances of the proposed motor, the finite element software is used to derive the vibration displacements of stator surface points. The output displacements of the points in time domain, which determines the contact state and contact time, are analyzed and compared. Then, a two-dimensional analytical model is constructed. The performances of stead rotation speed and stall torque are deduced. According to the simulated results, a prototype motor is manufactured and tested. The experimental results agree well with the simulation results, which verifies the effectiveness of the presented model.
