In this paper, a dual ring ultrasonic motor based on out of plane bending vibration mode is proposed, fabricated and characterized. This motor is composed of a stator constituted with two ring and one rod-shaped transducer at the middle and two disk shaped rotors. There are four piezoelectric ceramic plates are bolted at the middle of the rod-shaped transducer and used to excite the stator's blending...
A novel micro ultrasonic motor for multi-channel actuator control is proposed. It is composed of a stator constituted with a ring and two rod-shaped transducers and two cone shaped rotors. Two rod-shaped transducers have rectangular cross section, where four sets of piezoelectric element are bolted. Two sets excite longitudinal vibrations of the bars, and the other sets excite flexural vibrations...
The essay analyses overload characteristics of traveling wave type rotary ultrasonic motor. Establishing finite element model of the Traveling Wave Type Rotary Ultrasonic Motor under impact load and using finite element software (LS-DYNA) to simulate impact process of ultrasonic motor in a large overload system. Researching bearing overload capacity according to the current structure of ultrasonic...
