Abstract
An electrostatic motor and its method of production. This electric motor, comprising a fixed part (200, 204, 206, 208) called a stator with a deformable resilient membrane (208) and a moving part (230) called a rotor arranged on the membrane (208) and driven by deformation waves from the resilient membrane, is characterised in that it includes electrostatic means (204, 205) for deforming the membrane (208).
Claims11
An electric motor, comprising a fixed part (101) called a stator, a deformable resilient membrane (108, 208, 308, 408, 508) movably supported relative to the stator, and a moving part (230, 330, 430, 530) called a rotor arranged on the membrane and driven by friction between the rotor and the membrane, the friction being imparted by deformation waves in the resilient membrane, characterised in that it includes electrostatic means (104, 114, 122, 204, 304, 404, 504) for generating said deformation waves in said resilient membrane such that the rotor is moved in a plane parallel to an at-rest plane of the membrane.
An electric motor, comprising:
- a fixed stator (101) having a deformable resilient membrane (108, 208, 308, 408, 508);
- and
- a moving rotor (230, 330, 430, 530) arranged on the membrane and driven by friction, by deformation waves from the resilient membrane,
- characterized in that the motor includes electrostatic means (104, 114, 122, 204, 304, 404, 504) for deforming the membrane through exertion of electrostatic forces between a substrate and the membrane and capable of moving the rotor in a plane parallel to an at-rest plane of the membrane.
