Abstract
A linear uniphase polarized electromagnetic actuator. The actuator includes a coiled stator and one part which is movable in the direction OX with the useful travel of Xc. The movable part is moved according to the current traveling in the coil and the direction of travel depends on the direction of the current. The movable part includes a yoke of soft magnetic material having at least one magnet coupled with the yoke. The magnet is partially set inside a cavity of the mobile yoke on the side of the stator poles at a depth e such that 0.1 L<e<0.9 L, where E is the distance measured perpendicularly to OX between the stator poles and the cavity end pole.
