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 1^st longitudinal mode and 2^nd bending mode resonance frequency were about 360 kHz. The ultrasonic motor rotated 164rpm under the condition of an applied voltage of 20V_p-p.
