Theoretical analyses and experiments on ultrasonic motor driving fluid directly
,-0001,():
Being quite different from the contact ultrasonic motors, in the non-contact ultrasonic motor driving fluid directly the rotor immersed in the fluid doesn't contact with the stator directly. This motor solves many problems of the contact ultrasonic motor, such as shorter life expectancy and continuous running time, and becomes a new research direction in the field of the ultrasonic motor. This paper introduces the unique construction of this motor and the working mechanism. And then the course of transferring energy is discussed, in which the energy produced by the ultrasonic vibration is transferred to the rotor through the medium of fluid. It is revealed that the shearing Reynolds' stress is the driving force of the fluid flow. After that, this paper makes theoretical analysis on the acoustic streaming field and sets up the relationship between the acoustic streaming velocity and the rotating speed of the motor. Then the basic operating characteristics of the motor and the relationship between the rotating speed and the driving frequency, the driving voltage, the fluid circumstances and the rotor radius are simulated with MATLAB program. At last the simulation method is proved by experiments.
