Abstract
PURPOSE:To largely reduce noise suppressing the increase of the number of turns of conductive wire winding, by combining in such a way as to make the cross-sectional area of silicon steel plate larger than the cross-sectional area of non-crystal alloy plate of an iron core leg, and making other part of the iron core by the combination of contrary manner. CONSTITUTION:Iron core legs 3, 4 and yokes 1, 2 are made of silicon steel plates 7a, 7b and non-crystal alloy plates 6a, 6b. At the iron core legs 3, 4, 5 around which a coil is wound, the cross-sectional area of the silicon steel plate is larger than that of the non-crystal alloy plates. At other part of the core, the cross- sectional area of the non-crystal alloy plates is larter than that of the silicon steel plates, and the cross-sectional area of the iron core legs 3, 4, 5 around which the coil is wound is smaller than that of other part of the iron core with no winding.
