Abstract：Two degree-of-freedom spherical traveling wave ultrasonic motor is a kind of multi degree-of-freedom ultrasonic motor. The driving principle and basic structure of this kind of spherical ultrasonic motor are firstly introduced. Then some basic problems of motor are to be presented and structure of motor and optimal structure of stator and tuning devices are to be explained. Then this paper presents stator with big rake angle on outer edge and small rake angle on inner edge and tuning method of adjusting rake angle on outer edge of stator. Then contact model of the stator was set up for calculation of mechanical characteristics. Simulation and experiment results were verified for the stator. The diameter of prototype motor is 45mm in rotor and 30mm in stator and maximum output torque is 120mNm, maximum speed is 12r/min. From the abovediscussion and practical experiments availability of devices is to be verified. Results are used for designing theory and performance improvement of two degree-of-freedom spherical traveling wave ultrasonic motor.
