Abstract:
1. A rotating electric machine, comprising: a stator that includes a stator iron core having a plurality of stator slots, which are formed on the inner diameter side of the stator iron core, are spaced in a circumferential direction at predetermined intervals, and extend in an axial direction, and an armature winding provided in the stator slots; and a rotor disposed opposite to the stator with a predetermined gap therebetween, the rotor including a rotor iron core having a plurality of rotor slots, which are formed on the outer diameter side of the rotor iron core, are spaced in the circumferential direction at predetermined intervals, and extend in the axial direction, rotor bars, each of which is provided in one rotor slot, and end rings connected to the ends of the rotor bars; wherein each rotor slot is asymmetrically shaped in the circumferential direction with respect to a straight line drawn from a central axis of rotation of the rotor in a radial direction; wherein a slot opening is provided at the top of each rotor slot, the width of the slot opening being smaller in the circumferential direction than the width of the rotor slot; and wherein an outer corner of the rotor slot is machined, the outer corner being located behind in the rotational direction.
