Abstract
To obtain an electromagnetic device that is lightweight, has a simple structure, does not require a gap at the butt joint of the iron core, and has a wide range of variable inductance. [Solution] The electromagnetic device 101 comprises a first iron core 10 made of laminated steel plate around which a main winding 14 is wound, and a pair of first leg magnetic cores 12 and 13 extending in the same direction from a first base magnetic core 11; and a second iron core 20 made of laminated steel plate around which a control winding 24 is wound, and a pair of second leg magnetic cores 22 and 23 extending in the same direction from a second base magnetic core 21. The arrangement direction of the pair of first leg magnetic cores 12 and 13 and the arrangement direction of the pair of second leg magnetic cores 22 and 23 are orthogonal, and the lamination direction of the laminated steel plate of the pair of first leg magnetic cores 12 and 13 and the lamination direction of the laminated steel plate at the tips of the second leg magnetic cores 22 and 23 are orthogonal, and the tips of the pair of first leg magnetic cores 12 and 13 and the tips of the pair of second leg magnetic cores 22 and 23 are joined via a powdered magnetic core.
