    Abstract

    A rotary stepping ultrasonic motor driven by single-phase signal is proposed in this paper. It can realize driving and positioning under the same operating pattern to avoid miss steps and can solve the difficulty in designing a frictional interface between the stator and the rotor which is usually presented in the self-correction ultrasonic motors. Proposed rotary stepping ultrasonic motor is characterized by its no cumulative errors in open-loop control. Moreover,the construction of stator is designed with ANSYS software. Desiged prototype shows it runs steady without miss-step on trial, and the stall torque, stepping angle, and the error of one step are 0.003 2 N·m,7.5° and 0.6°, respectively.
