Abstract
A rotor includes a first slot, a second slot, a first flux barrier, and a second flux barrier. As viewed in a direction of the rotation axis of a rotor core, the substantially rectangular first and second slots are provided in a V-shape pattern. As viewed in the rotation axis direction of the rotor core, the first flux barrier is provided between first and second contact parts, and protrudes toward the outer circumference side from the outer circumferential short side of each of the first and second slots. As viewed in the rotation axis of the rotor core, an outer circumferential wall of the second flux barrier is continuous with the first contact part, and the second flux barrier protrudes from an inner long side of each of the first and second slots.
