An electromagnetic actuator includes a coil, a core designed to channel a flux of the coil so as to form a return path in an armature, the core having a base from which branches extend, including a central branch around which the coil extends, and two permanent magnets associated with the core so that the latter channels a flux of the permanent magnets so as to form a return path in the armature, the flux of the coil passing through the magnets. The two permanent magnets are placed in the central branch of the core so as to form a V, which separates the central branch into a support part, which supports the permanent magnets and is integral with the base, and an end part lying above the permanent magnets. The end part has an active face facing the armature in which a groove lies parallel to the permanent magnets. |
