PROBLEM TO BE SOLVED: To enlarge reluctance, to optimize motor torque, and to improve the efficiency of a motor in a permanent magnet type motor. SOLUTION: In an inner rotor type permanent magnet type motor, a rotor core 10 is composed first and second cores 13 and 16, permanent magnets 11 by the number of poles of the permanent magnet type motor are embedded and holes 12 for flux barrier are formed in the first core 13. Permanent magnets 14 in a number corresponding to that of the poles are embedded and holes 15 for flux barrier are formed in the second core 16. The permanent magnets 11 and the holes 15 are positioned opposite and are in a relation such that the holes 15 are contained in the slits (areas) of the permanent magnets 11. Permanent magnets 14 and the holes 12 are positioned oppositely and are in a relation such that the holes 12 are contained in the slits (areas) of the permanent magnets 14. |
