摘要：

In order to improve the fatigue life and performance, a new kind of ultrasonic motor constructed with a spiral blade rotor and Langevin transducer was proposed. Based on the longitudinal vibration effect between the vibrating face and the rotor blades, this paper analyzed the motion locus equation of the contact point and the drive mechanism of this kind of ultrasonic motor, and obtained characteristics of the rotor motion, and the relationships between driving force, torque, instantaneous rotary speed, average rotary speed of the motor and the structure, vibrating parameters. A test prototype was manufactured and tested to obtain the relationships between vibrator amplitude and driving voltage, preload force and rotor speed, torque and velocity. The test results show that when the driving voltage is 220 V, the vibrator amplitude is 11.15 μm, as the preload force is 150 N, the maximum no-load speed is 147 r/min; and as preload force is 250 N, the maximum torque is 225 N·mm. © 2014 Chinese Society for Electrical Engineering
