摘要： An electromagnetic relay includes a base frame including a main body supporting a fixed element, and a bottom plate having a plate thickness direction in an extending direction orthogonal to a central-axis line direction. An intermediate cover includes a covering plate facing a contact mechanism unit. An outer cover includes a top plate facing the bottom plate across the contact mechanism unit, and a first side plate extending from one end of the top plate and facing the covering plate. A first gap between the covering plate and the bottom plate in the extending direction and a second gap between the covering plate and the top plate in the extending direction are arranged to be substantially symmetric across the covering plate in the extending direction, the first gap and the second gap being on the first side plate.

摘要： A pre-fluxing system and method to reduce inrush current for a winding used in a transformer, motor or a solenoid. The system has a primary winding and a tertiary winding connected with a power source for providing electrical energy to these windings. A pre-fluxing circuit is connected to the tertiary winding. The power source provides electrical energy to the tertiary winding via the pre-fluxing circuit, and the pre-fluxing circuit pre-magnetizes the tertiary winding when energized. The tertiary winding is configured to pre-magnetize the primary winding to reduce inrush current when the power source energizes the primary winding.

摘要： An electromagnetic device includes a coil, a fixed iron core, a movable iron core configured to reciprocate to separate from the fixed iron core by a predetermined gap when a current applied to the coil is stopped and move to the fixed iron core by an attractive force when the current is applied to the coil, and a permanent magnet. The permanent magnet is arranged so that the permanent magnet is opposed to the gap in a second direction perpendicular to a first direction and separated from the fixed iron core and the movable iron core with a space interposed therebetween. A direction of a second magnetic flux generated by the permanent magnet conforms to a direction of the first magnetic flux between opposed surfaces of the fixed iron core and the movable iron core.

摘要： One embodiment describes a three-phase electromechanical switching device, which includes three single-phase switching devices mechanically and electrically coupled in parallel with one another. Each of the single-phase switching devices includes a direct current electromagnetic operator that receives a direct current control signal from control circuitry, in which the direct current control signal instructs the single phase switching device to open or close a single current carrying path in the single phase switching device at a desired time; stationary contacts disposed in a device housing; and a movable assembly that is displaced by energizing or de-energizing the electromagnetic operator, in which the movable assembly includes movable contacts that, with the stationary contacts, open and close the single current carrying path.

摘要： A self-holding magnet has a spring (accumulator spring) and a first armature. The self-holding magnet is capable of holding the first magnet armature against the spring force in a lift position which is determined by a stop. The stop determines a remaining air gap of a working air gap. The magnetic circuit of the self-holding magnet has a magnetic shunt with particularly low reluctance of the same order of magnitude as a series reluctance of the remaining working air gap(s). The working air gap(s) and the shunt are magnetically connected in parallel with the flow generated by a permanent magnet but in series with the flow generated by the trigger coil. The self-holding magnet additionally has at least one positive feedback device such as a compressible resilient stop or a shunt.
