<P>PROBLEM TO BE SOLVED: To provide a method for magnetizing a rotor of an electric machine. <P>SOLUTION: The method includes assembling an array of non-magnetized anisotropic permanent magnet segments 19 around a rotor spindle 18 encased in a metallic ring. The method also includes determining multiple optimal magnetization orientation directions of the non-magnetized anisotropic permanent magnet segments 19. Further, the method includes positioning the assembled non-magnetized anisotropic permanent magnet segments 19 around the rotor spindle 18 such that the optimal magnetization orientation directions of the non-magnetized anisotropic permanent magnet segments 19 are aligned with multiple flux lines produced by a magnetization fixture 12. Finally, the method includes energizing the magnetization fixture 12 for magnetizing the non-magnetized anisotropic permanent magnet segments 19 via a pulse direct current for an optimal duration of the pulse. <P>COPYRIGHT: (C)2011,JPO&INPIT |
