Abstract: In a rotary electric machine provided with a rotor and a stator, a wedge is inserted between in-slot portions stacked in each of slots of the stator and a wall of each of the slots. The wedge has two edges and a length ranging from one of the edges to the other. The length of the wedge is smaller than an axial length of the stator core. The wall is located oppositely to an opening of each slot. By inserting the wedge, both end portions of the conductors are tilted so as to be oriented oppositely to the rotor in the radial direction. The tilted end portions starts from each of the two edges of the wedge in the axial direction.

Abstract: A rotor includes a rotor core having a plurality of pairs of magnet-receiving holes and a plurality of magnets respectively received in the magnet-receiving holes. Each pair of the magnet-receiving holes is arranged in a substantially V-shape that opens toward a stator side. The rotor core also has a plurality of q-axis core portions through which q-axis magnetic flux flows, a plurality of first magnetic flux barriers and a plurality of second magnetic flux barriers. Further, in the rotor core, the following dimensional relationships are satisfied: W2≧W1; and W3≧W1, where W1 is a width between centerlines L1 of the q-axis core portions and the corresponding first magnetic flux barriers, W2 is a width between the centerlines L1 and the corresponding second magnetic flux barriers, and W3 is a radial width between a radially inner surface of the rotor core and the second magnetic flux barriers.
