The design of 60mm diameter plate type Rotary Ultrasonic Motor actuated by traveling flexural waves And Technology
Abstract: Ultrasonic Motor uses the effect of Piezoelectric from Piezoelectric ceramic, and it produce the effect of resonance excitation by the Active Materials. That the electrical energy transform to the micro-deformations. To propel the rotor and the drive shaft connected to it though the amplification of the micro-deformation of the active material that depends on friction at the interface between rotor and stator.The Ultrasonic Motor offer light mass, simply constructions, high torque density at low speed, low noise, efficient and actuate directly to the load. Ultrasonic motor in the aviation and aerospace, precision instruments, bio-medicine and a number of important areas has broad application prospects.
Projects adapted to the needs of the ultrasonic motor, In this paper, the design a 60mm diameter rotary traveling wave type ultrasonic motor, the main completed the following work:
Summary analysis of the domestic status of ultrasonic motor technology, development and the problems;
To explain the rotary traveling wave ultrasonic motor of the movement mechanism;
The use of ANSYS software, the establishment of a ultrasonic motor mathematical model, using the model of the work of the stator modal analysis and calculation to determine a 60mm diameter stator ultrasonic motor mode of work;
Completed a 60mm diameter ultrasonic motor assembly drawings and parts of the design plan;
Preparation of the stator of the machine process.
