摘要：PROBLEM TO BE SOLVED: To provide a rotor of a rotating electric machinecapable of cooling a magnetic pole portion while improving output performance of therotating electric machine. A rotor 10 of a rotating electric machine includes a rotor core20 and a magnetic pole portion 30. The magnetic pole portion 30 has at least two layers

of magnet portions 300 along the radial direction including an outer diameter sidemagnet portion 310 and an inner diameter side magnet portion 320. When viewed fromthe front, the rotor core 20 is arranged so as to overlap the d-axis between the outerdiameter side magnet insertion hole 410, the inner diameter side magnet insertion holes421 and 422, and the outer diameter side magnet portion 310 and the inner diameter sidemagnet portion 320. The second refrigerant passage hole 90 is provided, and theminimum width D9 of the magnetic path formed between the outer diameter sidemagnet insertion hole 410 and the second refrigerant passage hole 90 is the outerdiameter side magnet insertion hole. It is the minimum width D11, D12 or more of themagnetic path formed between 410 and the inner diameter side magnet insertion holes421, 422. [Selection diagram] Figure 2
