NEAR-RESONANCE ELECTROMECHANICAL MOTOR

摘要

An electronical 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 sef-centring of the different parts of the motor.
