Abstract

A micro ultrasonic motor using sector shaped piezoelectric ceramics vibrators has been designed and fabricated. This type micro motor has advantages, such as a high-torque driving, a low-profile, lightweight and compact structure. The outer diameter of vibrator was 9.8mm, the inner diameter was 5.2mm, and the thickness was 0.8mm. The vibrator's 1st longitudinal mode and 2nd bending mode resonance frequency were about 360 kHz. The ultrasonic motor rotated 164rpm under the condition of an applied voltage of 20Vp-p.
