A permanent magnet produces a magnetic field for the magnetic circuit and a holding force for holding the armature in the closed position. A coil is disposed to generate a magnetic flux in the same or opposite direction as the magnetic flux of the permanent magnet. The electromagnetic drive can be readjusted after installation, where the first and second yoke parts are moved relative to one another by the permanent magnet into the adjusted state, whereupon they are fixed in position. | 07-31-2014 |
