Abstract
A stator winding is formed by mounting winding bodies individually into pairs of slots of a stator core separated by a predetermined number of slots, the winding bodies each being formed by winding a jointless, continuous conductor wire coated with insulation for m turns into a helical shape such that end portions of rectilinear portions are linked by coil ends, where m is a natural number that is greater than or equal to two, and the coil ends include a top portion that displaces by a predetermined amount in a radial direction at an approximately central portion between the linked rectilinear portions, the radial displacement at the top portions is approximately a×d, where a is a natural number that is greater than or equal to 1 and less than or equal to (m−1), and d is a radial thickness of the rectilinear portions.
