Rotating electric machine

Abstract

This rotating electric machine comprises: a rotor that is provided with a plurality of magnetic poles including a plurality of flux barriers and a plurality of ribs; a stator that is provided with a plurality of teeth with a slot being formed between two adjacent teeth, the stator facing the radial outer side of the rotor with a predetermined gap therebetween; and a coil that is disposed in the slot. At least one flux barrier among the plurality of flux barriers is a central flux barrier disposed on a pole center line. An innermost circumferential position of the central flux barrier is disposed at a distance equal to or less than a length (h) in the radial direction of the teeth from the outer diameter toward the inner diameter side of the rotor. A distance (Wr) between two ribs disposed at both ends of the central flux barrier is equal to or greater than a shortest distance (Wt) in the circumferential direction of the teeth, and equal to or less than a distance (Ws) between a slot opening center, which is the center of an opening of a slot that opens to the inner circumferential surface of the stator, and a slot opening center of another slot adjacent to the slot (Wt≦Wr≦Ws).
