Abstract

An electromagnetic actuator comprising a core moving between a latched position and an open position, a permanent magnet, a coil designed to generate a first magnetic control flux to move the core from an open position to a latched position, and a second magnetic control flux designed to facilitate movement of the moving core from the latched position to the open position. The permanent magnet is positioned on the moving core so as to be at least partly outside the fixed magnetic circuit in which the first magnetic control flux flows in the open position, and to be at least partly inside the fixed magnetic circuit used for flow of a magnetic polarization flux of the magnet in the latched position.
