Abstract
A rotating electric machine includes an annular stator core with stator teeth. Each of the stator teeth has a pair of protruding portions that are formed at a distal end of the stator tooth so as to protrude from a main body of the stator tooth respectively toward opposite circumferential sides. Each of the stator teeth has a distal end surface radially facing a rotor. The circumferential lengths of the distal end surfaces of all the stator teeth are equal to each other. The stator teeth are classified into first and second groups. The protruding portions formed in the stator teeth of the first group are first protruding portions and the protruding portions formed in the stator teeth of the second group are second protruding portions. The first protruding portions have a different cross-sectional shape perpendicular to an axial direction of the stator core from the second protruding portions.
