The paper is to design a test incentive system for a new type of rotary ultrasonic motor called rotary ultrasonic motor with vibration type mosaic of the piezoelectric stator and rotor. The LabVIEW is used a development platform of the system, and the acquisition and control of input/output are carried out by the DAQ interface card and designed peripheral circuit. The system can output the amplitude, frequency and phase adjustable signals. The rotor position measured by the photoelectric encoder is fed back to the system to ensure that the mosaic position of stator and rotor can be kept when the ultrasonic motor starts next time. Experimental results show that this test system can fully meet the requirements for testing the new type of rotation ultrasonic motor.
