Abstract (en)
[origin: WO2010103218A1] The invention relates to an electromagnetic actuator with flux bypass, comprising a permanent magnet (5), a ferromagnetic armature (1), a keeper (2) which defines at least one air gap with the armature (1) and which can move between an open position and a closed position, mechanical return means for returning the keeper (2) to the open position, and at least one electric conductor capable of generating a magnetic flux in the armature (1). The actuator is characterised in that the armature (1) forms a closed magnetic loop in which the conductor(s) are capable of generating a magnetic flux. The magnet is disposed in the mobile keeper (2) and generates fluxes in two magnetic circuits in parallel, one of which comprises a portion of the armature (1), while the other is formed in the keeper (2) and comprises a plug area (7) that can be saturated by the magnet (5) or an air zone.
