Abstract:
A rotor (12) includes i) a stacked body (24) in which a plurality of holed steel plates (28a, 28b) provided with holes (29, 30) punched out of insulation coated steel plates are stacked together, and that includes a plurality of magnet holes (34) each of which is provided by the plurality of holes (29, 30) being connected together in an axial direction, and ii) a plurality of magnets (31n, 31s), at least one of which is arranged in each of the magnet holes (34). The plurality of holed steel plates (28a, 28b) include a first holed steel plate (28a) that contacts a first magnet (31n) that is one magnet, of two magnets (31n, 31s) that are adjacent in a circumferential direction from among the plurality of magnets (31n, 31s), and supports the first magnet (31n), at at least one circumferential portion, but does not contact a second magnet (31s) that is another magnet, and a second holed steel plate (28b) that contacts the second magnet (31s) and supports the second magnet (31s), but does not contact the first magnet (31n, 38n, 50n, 60n).
