    • An electromechanical motor according to the present invention has a stator with a drive element consisting of two serially connected bending sections and a central drive pad, for actuating on a body to be moved. The drive element extends parallel to the body. The drive pad and/or the body is elastic. Preferably, the drive pad has a lower stiffness than the body. The elasticity of the drive pad allows an assimilation of a part of the travelling wave energy applied to the drive element. The backbone of the stator is arranged to restrict the drive element from being removed from the body, but at the same time allow the drive element to be translated towards the body and even leave the mechanical contact with the backbone for shorter periods of time. Support means are preferably designed with convex surfaces in order to allow self-centering of the different parts of the motor.
    • 根据本发明的机电马达具有定子,其具有由两个串联连接的弯曲部分组成的驱动元件和用于在待移动的主体上致动的中心驱动垫。 驱动元件平行于主体延伸。 驱动垫和/或主体是弹性的。 优选地,驱动垫具有比主体更低的刚度。 驱动垫的弹性允许同时施加到驱动元件的行波能量的一部分。 定子的骨架被布置成限制驱动元件从主体移除,但是同时允许驱动元件朝向主体平移,并且甚至离开与骨架的机械接触更短的时间段。 优选地,支撑装置设计有凸起的表面,以允许电动机的不同部件自对中。
