Abstract: An alternator includes a stator having a stator core in which a plurality of slots are formed so as to line up in a circumferential direction on an inner peripheral wall surface, and a stator winding configured such that conducting wires are installed in the slots; and a rotor rotatably disposed inside the stator, having a field winding, a pair of pole cores each having a plurality of claw-shaped magnetic poles that alternately intermesh with each other disposed so as to cover the field winding, and a fan disposed on an axial end surface of at least one of the pole cores, air flows together with rotation of the rotor in stepped portions between teeth partitioning the slots, and an inclined portion bent in a circumferential direction of the stator is formed on at least one of the teeth on at least one end portion among first and second axial end portions of the teeth.
