| PURPOSE: To provide a specified kind of conveniently formed electromagnetic actuators with minimized eddy current by composing magnet structure of inside and outside loop-shaped members, which are formed from winding wire slender piece shaped materials, and a loop-shaped bridging member for mutually connecting one end of the inside loop-shaped member to the adjacent terminal part of the outside loop-shaped member. CONSTITUTION: This actuator is composed of magnet structure 10 and a armature 11, the magnet structure 10 is provided with a loop-shaped winding wire 12 and when operating the winding wire, an opposite magnetic pole and loop-shaped magnetic pole faces 13A and 14A are formed. The armature 11 is separated from the magnetic pole face, magnetic flux passed between the magnetic pole face and the armature generates attracting force between the armature 11 and the magnet structure 10, and the magnetic pole faces are respectively formed at one end of magnetic pole pieces 13 and 14. The magnetic pole piece is formed from inside and outside loop- shaped members 15 and 16, and the magnet structure 10 further includes a loop-shaped bridge member 17 for magnetically coupling the terminal parts of loop-shaped members away from the armature 11. The members 15 and 16 and the bridge member 17 are formed from magnetic materials. Thus, the eddy current caused by a change in magnetic flux during use of actuator is minimized.

| PURPOSE:To make the gap interval between both end surfaces variable due to the elasticity of an iron core by bending the flexible iron core bundled with plural elementary wires and equipped with a coil wound around the iron core to nearly a ring shape. CONSTITUTION:A variable reactor 20 has a nearly ring shape iron core 21 which has a gap 24 and a coil 22 is wound around part of the iron core 21. The iron core 21 is made of bundled plural thin elementary wires 23 and is bent to become nearly a ring shape and to have a gap 24 between both the end surfaces 25, 25 which face each other. Each elementary wire 23 is made of a flexible ferromagnetic material the surface of which is electrically insulated. Consequently, the iron core 21 itself is given elasticity. The interval l' of the gap 24 can be varied by moving both the end surfaces 25, 25 or either one end surface 25. This varies the magnetic reluctance in a magnetic path and the reactance of the coil 22 is adjusted. | ||||||
