Claim 0:
1. A rotor comprising:
an electromagnetic steel sheet including a first magnet insertion hole, a second magnet insertion hole, and a center rib between the first magnet insertion hole and the second magnet insertion hole, the first magnet insertion hole and the second magnet insertion hole being arranged in a V shape in a plane orthogonal to an axial direction;
a first permanent magnet disposed in the first magnet insertion hole; and
a second permanent magnet disposed in the second magnet insertion hole, wherein
the rotor satisfies T≤W1≤2×T≤W2, W1<W2, and 0.9≤W1/T≤1.9,, where T is a thickness of the electromagnetic steel sheet, W1 is a minimum width of the center rib in a direction orthogonal to a radial direction, and W2 is a maximum width of the center rib in the direction orthogonal to the radial direction, wherein
a location having the minimum width W1 is a radially outer end of the center rib.
