| Abstract: | The working principle of vibrator with bi-contact surface was analyzed. Finite element analysis of different kinds of vibrators was done. The vibrator structure was approved by the harmonic analysis of the amplitude of vibrator. The result showed performance of the motor with inner circle fixed vibrator was better than the motor with outer fixed vibrator. Also,piezoelectric ceramic affixed inside the tooth ring was better than outside when the external diameter of the vibrator is the same. |
