PROBLEM TO BE SOLVED: To provide a rotor for permanent magnet embedded type motor, capable of preventing degradation in demagnetization resistance while suppressing noise.SOLUTION: The rotor 1 for permanent magnet embedded motor includes a core 5 with a plurality of magnet insertion holes 3 and a plurality of permanent magnets 9 stored in each of the plurality of magnet insertion holes. The core is formed with slits 21 between the respective magnet insertion holes and an outer surface 5a of the core, and the magnetization orientation of each of the permanent magnets is inclined relative to the magnetic-pole center line. |
