    Abstract: Die Erfindung betrifft einen Elektromagneten (1) mit mehreren Induktionsspulen (3, 4), insbesondere mit zwei Induktionsspulen, und mit einem Anker (6), der sich in Kraftrichtung der Induktionsspulen (3, 4) erstreckt und auf den abhängig von der Bestromung der Induktionsspulen (3, 4) eine magnetische Kraft ausgeübt werden kann, um den Anker (6) entlang der Kraftrichtung zu verlagern. Erfindungsgemäß ist mindestens ein Permanentmagnet (8) zwischen den Induktionsspulen derart positioniert, dass der ferromagnetische Anker (6) an seinen beiden Enden (10, 11) gleichpolig ausgebildet ist.

    Abstract: An electromagnetic actuator with flux feedback control includes two poles located on opposite sides of a soft-magnetic target. A bias flux is introduced that flows into both poles. Magnetic circuitry may be designed so that the total bias flux is independent or substantially independent of a position of the target with respect to the poles or the control flux. The electromagnetic actuator also includes flux sensors introduced into each gap between the poles and the target. The electromagnetic actuator further includes an actuator control circuit to command the current in the control coil to bring a difference between the readings of the two flux sensors to a targeted level. In some aspects, the force exerted on the actuator target in this arrangement may be proportional to the command signal regardless of the position of the actuator target, MMF drop in the soft-magnetic parts of the magnetic circuit, or the frequency.

    Abstract: The invention relates to a drive system (20) for a circuit breaker. The drive system comprises an electromagnetic actuator (10) having a first coil (14), a second coil (15), an armature (12) arranged to be movable between a first and a second end position by means of the coils (14, 15), and permanent magnets (13) arranged to keep said armature (12) locked at said first and second end positions. In accordance with the invention both coils (14, 15) are energized simultaneously for effectuating the movement of the armature (12) between the two end positions, one for neutralizing the permanent magnet and one for attracting the armature. This is in contrast to prior art, wherein the coils are energized one at a time; one coil for moving the armature to one of the end positions and the other coil for moving the armature to the opposite end position. The energizing of neutralising coil is initiated before the energizing of the attracting coil.

    Abstract: An apparatus for detecting troubles with a solenoid-operated device that includes two current paths consisting of two pairs of series switches (10, 20, 30, 40) and an electromagnetic coil (1) connected between the intermediate nodes (2, 4) of the pairs. The existence of a trouble with the solenoid-operated device is decided based both on the state of operation of the switch pair and on the magnitude of the voltage signal corresponding to the sum of a first voltage signal (VP) and a second voltage signal (VN) corresponding, respectively, to potentials at the intermediate nodes (2, 4).
