Abstract:
A stator for an electric rotating machine includes a stator core that has slots, a stator coil, and an impregnant applied to the inner surface of the stator core. The stator core has a plurality of teeth that divide the slots. Teeth having chamfered surfaces between a projected tip surface and each side surface of the teeth and teeth without chamfered surfaces are intermingled. At least one bent corner part formed at an end of the projected tip surface of the teeth is formed in an arcuate surface. A relationship (R1>R2) is satisfied, where R1 represents a curvature radius of arcuate surfaces formed in the curved corner part where the projected tip surface and the chamfered surface abut and R2 represents a curvature radius of the arcuate surfaces formed in the curved corner part where the projected tip surface and the side surface abut.
