Abstract (en)
[origin: WO2011042273A1] Known electromagnetic actuators comprising permanent magnets often have the disadvantage that returning the tappet is often not possible solely by way of permanent magnetic forces, when a distance of over 1 mm between the armature and core must be overcome. According to the invention, an actuator is proposed, in which the permanent magnet (32) is arranged in a stationary manner within the electromagnetic circuit (4) and means (34, 40) are designed for focusing axial magnetic field lines on the permanent magnetic circuit (8).
