PROBLEM TO BE SOLVED: To provide a concentrated winding coil which suppresses impairment of the insulating coating of a conductor.SOLUTION: A concentrated winding coil 20 consisting of a plurality of layers includes an outer single-layer coil 21, and an inner single-layer coil 22 coming into contact with the inner peripheral surface of the outer single-layer coil 21, and fitted and fixed in place. The outer single-layer coil 21 and inner single-layer coil 22 are subjected to single-layer winding independently from each other, and the conductors of both coils 21, 22 adhere each other to constitute a concentrated winding coil of a multiple layers.SELECTED DRAWING: Figure 2 |
