Abstract
A new type ultrasonic motor is presented to avoid the shortcoming such as operating unbalance and low-torque of the traditional ultrasonic motor.It is different from some traditional motors whose rotor and stator are in frictional contact by several points during the dynamic process,and the rotor and the stator are in contact by the line during the dynamic process.It presents the structure of the motor and the driving circuit,the excited method of this motor is described in details.By use of finite element software ANSYS,vibrating frequency and mode of stator of the motor is analyzed.The performance of this motor is obtained through the experiment.
