Abstract
In this paper, disk-type ultrasonic motor using radial and bending vibration modes is newly designed and fabricated to measure its characteristics. As the diameter of elastic body increases, the resonant frequency decreases and its resonant frequency is about 92kHz when the physical dimensions of piezoelectric ceramic and elastic body are 28mm of diameter and 2mm of thickness, and 32mm of diameter and 2mm of thickness, respectively. When the applied voltage is 20Vpp. its speed and torque are 200rpm and 1N, respectively.
