Abstract
A strand of a unit coil of an armature coil is transposed by transposition angle 540 degrees in a slot and transposed by a first transposition angle at coil end portions. In the slot, the strand has a change portion in which the change rate of transposition of the strand is changed. An axial-direction middle point of the change portion is located between a position at transposition angle 90 degrees and a position obtained by adding the first transposition angle of the strand to transposition angle 90 degrees.
