PURPOSE:To reduce leakage inductance and prevent the power factor from being lowered, by making each winding diameter of a plurality of coil units belonging to the same phase different from one another, and by enabling the units to be fit together on the same plane. CONSTITUTION:A winding consists of five coil units 11, for example, and each coil unit 11 is organized by being wound up on each conductor plural times and by being provided with insulating coat. Each winding diameter of each coil unit 11 is different from one another, and inside the coil unit 11 of larger diameter, the coil unit 11 of smaller diameter is fitted, and as the result, each coil unit 11 can be contained on the same plane. One end 12 is led out of one section outside the coil units 11 of the largest diameter, and another end 13 is led out of one section inside the coil unit 11 of the smallest inner diameter. |
