    • 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.
    • 本发明提供一种用于磁体嵌入式电动机和磁体嵌入式电动机的转子a,由此可以在确保所需矫顽力和磁通密度的同时大大降低其制造成本。 一种用于嵌入磁体的电机的转子,其包括嵌入其中的多个永磁体21,其中每个永磁体21形成有多个磁场A至D,其具有不同的矫顽力,该矫顽力是根据逆磁场强度确定的 只要具有相对较大的矫顽力的磁性区域被指定为受相对较大的反向磁场影响的区域,其作用在每个永磁体21上。
