Survey of the Various Operating Principles of Ultrasonic Piezomotors
نویسندگان
چکیده
Piezoelectric ultrasonic motors have been known for more than 30 years. In recent years especially, a large number of different designs have been developed, both for rotation and linear drives. This talk will provide a definition of piezoelectric ultrasonic motors and classify their different operating principles. The operation of each type will then be explained, commercially available implementations described and the advantages and disadvantages of each discussed. The goal is to provide an international perspective on the current state of development of piezoelectric ultrasonic motors.

متن کاملMinimising heat dissipation in ultrasonic piezomotors by working in a resonant mode
Heat dissipation in ultrasonic motors should be limited, especially in precision applications since it causes thermal deformations. Therefore, n easy-to-understand mechanical model was developed to simulate heat dissipation in an ultrasonic motor. This model involves the dielectric, iezoelectric and mechanical hysteretic losses of the piezoelectric material. Both the model and the experiments l...
