PURPOSE:To utilize a space effectively and intensify a magnetic field, by winding the least-sectional coil conductor of a trapezoidal section in a single row only as for a double-row multilayer electric winding of the parallelled coil conductor. CONSTITUTION:As for an electric windings of double-row multilayer made of a plurality of windings of parallelled coil conductors, only a conductor 9 of the thinnest layer in coil width among trapezoidal cross sections 1 on a predetermined circular position is made a single row. In making the innermost layer a single row, a power supply terminal 6 is provided on the outermost layer. In making the outermost layer a single row the power supply terminal 6 is provided on the innermost layer. The connection between a single row of one layer and the other double-row layer is done as a double row for a part of layers in a single layer and a single row. However, this part is mounted to a rectangular cross section, and so the outermost or innermost layer of trapezoidal cross section 1 is made a single layer and a single row. This makes the conductor arrangement on the trapezoidal cross section without extremely thinning the coil width. As a result it utilizes a space effectively and intensifies a magnetic field. |
