Abstract
Provided is a rotating electric machine. Angles formed by tooth center axes of adjacent teeth are defined as tooth pitch angles. Maximum tooth pitch angles are defined as first tooth pitch angles α. At least one of tooth pitch angles become smaller as proceeding from the first tooth pitch angles αin a clockwise direction and a counterclockwise direction, respectively, and such tooth pitch angles are defined as second tooth pitch angles α. Cross-sectional areas of second coils, which are arranged in slots each formed between adjacent teeth corresponding to the second tooth pitch angles αin a cross-section perpendicular to a rotation axis, is smaller than cross-sectional areas of first coils, which are arranged in slots each formed between adjacent teeth corresponding to the first tooth pitch angles αin the cross-section perpendicular to the rotation axis.
