Abstract (en)
[origin: EP1811536A1] The actuator has a coil (14) enclosed by a magnetic circuit (10). The circuit is formed of a mobile frame (21) with a flange (18) and a fixed part (20) including a yoke (22) enclosing a flange (17) and a permanent magnet (13). The magnet is placed at an end of an intermediate leg (11) of a side of the flange of the yoke. A magnetic flux is established between the frame and the fixed part and directed in a displacement direction of the frame. The frame and the fixed part have a complimentary shape at the level of legs (11, 12.1, 12.2). A flux guiding part is inserted in the leg (11).
