Claim 2:
3. The rotor according to claim 1, wherein
the electromagnetic steel sheet includes a first thin-wall portion between an outer peripheral surface of the electromagnetic steel sheet and the first magnet insertion hole,
the electromagnetic steel sheet includes a second thin-wall portion between the outer peripheral surface of the electromagnetic steel sheet and the second magnet insertion hole,
the first magnet insertion hole includes a first flux barrier that is a space between the first permanent magnet and the first thin-wall portion,
the second magnet insertion hole includes a second flux barrier that is a space between the second permanent magnet and the second thin-wall portion, and
the rotor satisfies 0.6≤W3/T≤1.5 and 0.6≤W4/T≤1.5, where in the plane, W3 is a minimum width of the first thin-wall portion in a first radial direction and W4 is a minimum width of the second thin-wall portion in a second radial direction.
