摘　　要：新型驻波直线超声电动机采用面内振动的形式,利用单一弯曲模态实现直线电动机的正、反方向驱动。分析了电机的工作原理,通过有限元软件进行动态设计,研制了模型样机,为环形驻波直线超声电动机的设计提供了理论依据。A novel standing-wave linear USM was presented, which used in-plane vibration. Two same orders bending modes can be used to realize movement of forward and backward, respectively. The working principle was analyzed. The motor was dynamic designed with the finite element analysis software. The prototype was manufactured which offered as theoretical basis for designing the ring-type standing-wave linear USM.
