摘要： The DC operated polarized electromagnet includes a spool around which an excitation coil is wound and that has a central opening, a plunger having first and second armatures, fitted individually, an outer yoke enclosing opposing side faces of the spool so as to attract the first armature, an inner yoke arranged on the inner side of the outer yoke so as to attract the second armature, and permanent magnets arranged between the outer yoke and the inner yoke, and reduces magnetoresistance by setting the thickness of the outer yoke thicker than the thickness of the inner yoke so that convergent magnetic flux in the plunger is diverted into the outer yoke.

摘要： An electromagnetic drive for an electrical switch such as a circuit breaker, has at least one movable armature that can implement a lifting movement along a pushing direction for moving a movable switching contact of the switch. In a closed armature position, the armature closes a magnetic circuit through first and second magnetically conductive yoke parts. 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.

摘要： A linear solenoid has a first magnetic pulling portion for attracting a forward end of a plunger in a forward direction. The linear solenoid further has a second magnetic pulling portion at a rear end of the solenoid. A magnetic path portion is formed at the rear end of the solenoid and composed of a constant overlapping area and a temporal overlapping area. A plunger side-gap portion is formed at a rear end of the plunger so as to face to the overlapping areas in a radial direction. A first radial gap, which is formed between the constant overlapping area and the plunger side-gap portion, is made larger than a second radial gap, which is formed between the temporal overlapping area and the plunger side-gap portion.

摘要： An electromagnet composed of a coil, a movable iron core adapted to move on the center axis of the coil, and a stationary iron core provided so as to cover the upper and lower surfaces and the outer peripheral surface of the coil, characterized by a permanent magnet arranged in a gap surrounded by the movable iron core and the stationary core, wherein the movable iron core is attracted by the stationary iron core by a magnetic field created by the permanent magnet, thereby it is possible to solve a problem inherent to a conventional electromagnet such that a permanent magnet is directly energized in a reverse direction during release operation so as to cause demagnetization of the permanent magnet. That is, since the permanent magnet is arranged in the gap surrounded by the movable iron core and the stationary iron core, the magnetic filed can be prevented from affecting upon the permanent magnet, thereby it is possible to provide an electromagnet having a long use like and a high degree of reliability with no demagnetization of a permanent magnet.
