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 around a rotor spindle encased in a metallic ring. The method also includes determining multiple optimal magnetization orientation directions of the non-magnetized anisotropic permanent magnet segments. Further, the method includes positioning the assembled non-magnetized anisotropic permanent magnet segments around the rotor spindle such that the optimal magnetization orientation directions of the anisotropic permanent magnet segments are aligned with multiple flux lines produced by a magnetization fixture. Finally, the method includes energizing the magnetization fixture for magnetizing the segments via a pulse direct current for an optimal duration of the pulse.
