ELECTROMAGNETIC ACTUATOR |
摘要 |
<p>Electromagnetic actuator for operating at least one movable contact of a switch into a switched-on position or a switched-off position. The electromagnetic actuator (1) has a first magnetic circuit for making a movable (3) and a fixed (4) pole body move towards one another and a second magnetic circuit, separate from the first magnetic circuit, with a permanent magnet (9) and a retaining plate (10). A switching-off coil (15) operates to counteract the magnetic field in the second magnetic circuit so that the actuator (1) can return to a switched-off position. In the axial direction of the actuator (1), the switching-off coil (15) is positioned Gloser to the retaining plate (10) than the permanent magnet (9), as a result of which more effective operation of the actuator is possible. Furthermore, the actuator is constructed from cylindrical elements that are easy to produce and to assemble.</p> |
