Abstract
A stator of ultrasonic motor of high torque with a new configuration is proposed. The stator designed newly is two sided vibrator consisting of toothed metal disk with piezoelectric ceramic ring bonded on both face of disk. which generates a flexural traveling wave along the circumference of disk. it produces a large vibrating force and amplitude because the vibrator is sandwiched by two piezoelectric ring. The finite element method was used to compute the vibration mode of the stator with a outer diameter of 48mm. A 6th vibration mode was chosen as operation mode with resonance frequency about 72kHz. According to the design, the prototype stator was fabricated and its performance was measured.
