Abstract (en)
[origin: EP1655755A1] The actuator has a moving vane (20) mechanically connected to a moving coil (30) and including an air gap surface for forming a magnetic air gap of thickness variable with an air gap surface corresponding to a fixed yoke (20). A residual magnetic air gap of constant thickness is formed by two airgap surfaces. An electric current controlling unit controls the position and the speed of the coil and the vane. An independent claim is also included for an electric switch device including an electromagnetic actuator.
