Design and Fabrication of Linear-Type Ultrasonic Motor using Ll-B4 Vibration Mode
Ll-B4 진동모드를 이용한 linear-Type Ultrasonic Motor의 설계 및 시작
Abstract
A plate-type ultrasonic linear motor using longitudinal and bending multi-vibration mode was designed and fabricated for card-forwarding device. The rotor consisted of piezoelectric ceramic plate and elastic materials. The performances of the motor were measured. As the experimental results, no-load speed of the motor was 0.6 m/s at 80 V in applied voltage. Starting torque was 1.4 mNm and maximum efficiency was 1.2 %.
