| Abstract: | The motor introduced in this paper is a new style in the field of piezoelectric ultrasonic motor.It is different from contact type ultrasonic motor,the rotor swimming in fluid isn't in contact with the stator directly.The energy produced by the piezoelectric vibration is transferred from the stator to the rotor through the fluid medium.So the rotor rotates by the energy.The structure and the driving circuit of non-contact type piezoelectric ultrasonic motor are introduced in this paper.The operating principle of the motor is also analyzed.The existent problems and the future development are discussed at last. |
| Keywords: | non-contact type piezoelectric ultrasonic motor fluid medium |
