| Abstract: | Three Key techniques:selection of style of ultrasonic motor,consistency between longitudinal and torsional vibration modal frequency and rationality of installation position of piezoids in ultrasonic motor, in design of brush type ultrasonic motor using longitudinal and torsional vibration modes are disussed in detail in the paper. The solutions of the three Key issues are presented. According to these ideas, an optimum performance unltrasonic motor using longitudinal and torsional vibration modes is introduced. |
