摘要
介绍了超声波马达的新进展——非接触型超声波马达,其定子和转子是非接触的,因而克服了接触型超声波马达转速低和寿命短的缺点。文中介绍了国外非接触超声波马达的研究现状,并对其进一步的研究方向作了探讨。
In this paper,new development of ultrasonic motor,non contact ultrasonic motor,is introduced.Its stator and rotor are separated,thus overcomes the shortcomings of low revolution speed and short life span in contact ultrasonic motor.Several non contract ultrasonic motors abroad are given,and the further research directions are discussed.
