PROBLEM TO BE SOLVED: To provide a magnet-embedded rotor capable of reducing the gap between the split cores as much as possible, while facilitating the management of the dimensions of the split core.SOLUTION: A rotor 4 includes a cylindrical rotor core 40, and permanent magnets 50, 51 embedded in the rotor core 40. The rotor core 40 is constituted by assembling a first core member 41 and a second core member 42 so that a first split core 41b having a N pole on the outside where a permanent magnet 50 is embedded, and a second split core 42b having a S pole on the outside where a permanent magnet 51 is embedded adjoin mutually in the circumferential direction of the rotor core 40. Each side face 41f inclining to one side of the rotor core 40 in the axial direction is formed on the side face 41f of the first split core 41b. Each side face 42f inclining to the other side of the rotor core 40 in the axial direction is also formed on the side face 42f of the second split core 42b facing the side face 41f of the first split core 41b.SELECTED DRAWING: Figure 2 |
