Patent ID: 11404924

Abstract:
There is provided a rotor that is capable of improving torque and rotational speed while securing mechanical strength. The rotor is equipped with a plurality of outer radial-side magnet slots 12, 13, a plurality of inner radial-side magnet slots 14, 15, a plurality of outer radial-side magnets 21, 22 that are respectively fit into the outer radial-side magnet slots 12, 13, and a plurality of inner radial-side magnets 23, 24 that are respectively fit into the inner radial-side magnet slots 14, 15. Lb2>Lb1 is satisfied, when one 12c, 13c of the recesses 12a-12d, 13a-13d of the outer radial-side magnet slot 12, 13 that is closest to the d-axis has a radial length of Lb1, and when one 14d, 15d of the recesses of the inner radial-side magnet slot 14, 15 that is closest to the d-axis has a radial length of Lb2.
