PROBLEM TO BE SOLVED: To enlarge the reluctance torque of a permanent magnet type motor and to improve the efficiency of the motor. SOLUTION: In an inner rotor-type permanent magnet type motor, a first core 13 where the permanent magnets 11 and 12 of respective magnetic poles are embedded and a second core 17, where holes 14 and 15 are formed in places corresponding to permanent magnets 11 and 12 and holes 16, are formed for the respective magnetic poles along the outer diameter side of the core 10 are overlapped by adjusting them to (d) and (q) shafts, so as to constitute a rotor core 10. In a first core 13, the two permanent magnets 11 and 12 are embedded into a chevron-shape with respect to a q-axis in a plane near the center line of the magnetic poles. A second core 17 has holes for flux barrier 14 and 15, which are contained in the holes of the permanent magnets 11 and 12 and the holes for a reluctance adjustment 16, which are dislocated from the holes 14 and 15 for flux barrier and are positioned in the outer diameter side of the rotor core 10, for the respective magnetic poles. |
