ROTOR FOR MAGNET-EMBEDDED MOTOR AND MAGNET-EMBEDDED MOTOR |
摘要 |
The present invention provides a rotor a for magnet-embedded motor and a magnet-embedded motor whereby the manufacturing cost thereof can be significantly reduced while securing desired coercive force and magnetic flux density. A rotor for a magnet-embedded motor which comprises a plurality of permanent magnets 21 embedded therein, wherein each permanent magnet 21 is formed with a plurality of magnetic regions A to D having different coercive forces that are determined based on the intensity of the inverse magnetic field that acts on each permanent magnet 21, provided that a magnetic region having a relatively large coercive force is designated to be a region that is influenced by a relatively large inverse magnetic field.
