Abstract
An armature winding includes a plurality of distributed winding bodies that are each produced by winding a single conductor wire that is insulated, jointless, and continuous, and that has a constant cross-sectional area perpendicular to a longitudinal direction, the conductor wires include first through third coil end portions that link first through fourth rectilinear portions and first through fourth rectilinear portions, and are formed such that radial widths w' of the first through fourth rectilinear portions are wider than radial widths w of the first through third coil end portions, and first gaps are formed between radially adjacent coil end portions to allow a cooling medium to pass through the first gaps.
