PROBLEM TO BE SOLVED: To provide a permanent magnet motor capable of using a rotor core of a permanent magnet motor of a usual IPM structure for a rotor core of a consequent pole type.SOLUTION: A permanent magnet motor 30 includes a rotor 10 formed by forming a plurality of magnet embedding holes 12a, 12b, 12c, 12d, 12e and 12f with a predetermined interval in a circumferential direction of a rotor core 16 formed in a cylindrical shape by laminating steel plates. By alternately embedding in the circumferential direction permanent magnets 13a, 13c and 13e and soft magnetic materials 13b, 13d and 13f with reference to the magnet embedding holes 12a, 12b, 12c, 12d, 12e and 12f, a rotor of a consequent pole type is formed.SELECTED DRAWING: Figure 1-1 |
