摘要
A method for magnetizing a rotor of an electrical machine is provided. 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 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 segments (19) via a pulse direct current for an optimal duration of the pulse.
