    • PROBLEM TO BE SOLVED: To provide a magnet and a rotary machine that not only solve problems caused by split magnets, but also have an optimum coercive force distribution (residual flux density distribution).SOLUTION: A magnet 31 has a surface 34 adjoining a stator 11. When a rotary machine 1 functions as a motor, a demagnetizing field is applied to an opposite-side part of the surface 34 in a rotating direction R shown in Fig. 2 during rotation in the rotating direction R. When the rotary machine 1 functions as a dynamo, the demagnetizing field is applied to a part of a rotor 21 on a side in the rotating direction R. In those cases, the demagnetizing field has a maximum value at the part of the surface 34 of the magnet 31, and decreases inwardly in the magnet 34. The demagnetizing field having such a distribution is applied to the magnet 31, so a diffusion area 32 is formed at a part of the surface 34. In the diffusion area 32, a heavy rare-earth element such as Dy and Tb is diffused inwardly from the surface 34 and coercive force decreases inwardly from the surface.
    • 解决的问题:提供不仅解决由分割磁体引起的问题,而且具有最佳的矫顽力分布(剩余磁通密度分布)的磁体和旋转机械。 解决方案:磁体31具有与定子11相邻的表面34.当旋转机1用作电动机时,在图3所示的旋转方向R上的表面34的相反侧部分施加去磁场 。 在旋转方向R旋转时,当旋转机1作为发电机起作用时,在旋转方向R侧的转子21的一部分上施加去磁场。在这些情况下,退磁场为最大 在磁体31的表面34的一部分处的值,并且在磁体34中向内减小。具有这种分布的退磁场被施加到磁体31,因此在表面34的一部分处形成扩散区域32。 在扩散区域32中,诸如Dy和Tb的重稀土元素从表面34向内扩散,并且矫顽力从表面向内减小。 版权所有(C)2012,JPO&INPIT
