description According to the present invention, a stator has stator slots and stator teeth. A rotor has rotor slots, rotor teeth, and rotor slot tips projecting in a circumferential direction from the ends in the circumferential direction of the rotor teeth by a prescribed length in a radial direction. The relationship of Nss ≥ Nrs is satisfied, where Nss represents the number of stator slots, and Nrs represents the number of rotor slots. The relationships of Tst ≤ Trt and (Wst - Wrs) + 2 × Dtip ≥ Wst are satisfied, where Wst represents the minimum widths of the stator teeth in the circumferential direction, Wrt represents the average width of the rotor teeth between rotor bars in the circumferential direction, Wrs represents the average width of the rotor slots in the circumferential direction, Tst represents a total of the minimum widths Wst of all the stator teeth, and Dtip represents the length of each of the rotor slot tips in the radial direction.
