| titleOfInvention | Magnet embedded rotor, electric motor, and assembly method of electric motor |
| abstract | According to one embodiment, a magnet embedded rotor includes a rotor iron core (11, 211, 311) and a permanent magnet (30, 430). The rotor iron core (11, 211, 311) is formed of a magnet into a cylindrical shape and provided with holes. The rotor iron core (11, 211, 311) includes a nonmagnetic portion (23, 423), salient poles (22, 422), a notch groove (26, 426), a bridge (25, 425), and a first protrusion (27, 427). The nonmagnetic portion (23, 423) prevents magnetic-flux short circuiting. The salient poles (22, 422) are located on the outer circumferential side of the holes. The notch groove (26, 426) is located between an adjacent pair of the salient poles (22, 422). The bridge (25, 425) is located between the notch groove (26, 426) and the nonmagnetic portion (23, 423). The first protrusion (27, 427) protrudes outward from the center of the notch groove (26, 426). The permanent magnet (30, 430) is embedded in each hole. The radius of each salient pole (22, 422) gradually decreases from the center toward the notch groove (26, 426). The radius of the first protrusion (27, 427) is equal to that of the center of the salient pole (22, 422). |
