【Abstract】 This paper discusses the main testing techniques and methods of ultrasonic motors in details for the first time.We use those to measure the resistance of free stator,vibration testing of stator and the output relation ship between torque and the speed or efficency of the ring type traveling wave ultrasonic motors with 30 mm diameter made by ourselves.Through the measurement techniques and methods for realization,not only the proportion of the function and the cost is superiority,but also other type USM can use and they provide fundamental basis and experimental verification for control strategy,closed loop control and the practicality of ultrasonic motors.更多还原
