Japanese Patent JP7427512
Kind Code:
B2
Abstract:
To provide an electromagnetic apparatus that requires a small number of windings, is lightweight and has a simple structure, and enables significant change of an impedance (a reactance).SOLUTION: An electromagnetic apparatus 10 includes: a first iron core 11 having a plurality of first leg magnetic cores 11b, 11c extending in the same direction from a first base magnetic core 11a and being formed from a laminated steel plate around which a main winding 13 is wound; and a second steel core 12 having two second leg magnetic cores 12b, 12c extending in the same direction from a second base magnetic core 12a and being formed from a laminated steel plate around which a control winding 14 wound. In the first iron core 11 and the second iron core 12, in a state where an arrangement direction of the first leg magnetic cores 11b, 11c is orthogonal to an arrangement direction of the second leg magnetic cores 12b, 12c, tips of the plurality of first leg magnetic cores 11b, 11c come in contact with tips the two second leg magnetic core 12b, 12c, and a lamination direction of the laminated steel plate of the first leg magnetic cores 11b, 11c and a lamination direction of the laminated steel plate of the second leg magnetic cores 12b, 12c on the contact face are arranged in the same direction.SELECTED DRAWING: Figure 1
