ROTOR FOR ROTARY ELECTRIC MACHINE |
摘要 |
A rotor (1) for a rotary electric machine includes a rotor core (2) including a first core portion (20) having a plurality of core pieces (5, 6) joined together through caulking portions (2a) and a hollow first lightening portion (20a), and a second core portion (21) having a plurality of core pieces (7, 8) joined together through caulking portions (2a) and a press-fit portion (21 b). A radial magnetic path width of a ring-shaped outer circumferential portion formed by laminating the first core portion (20) and the second core portion (21) changes along a circumferential direction of the rotor core (2). Therefore, a weight and an inertia can be reduced. |
