被动磁轴承（永磁轴承）的永久磁铁环经常采用的磁化方式有两种，即径向磁化和轴向磁化．就径向磁化的被动磁轴承而言，由于要实现一个强大的放射状径向磁场比较困难，因此要完成对高磁能指标、体积较大的整体永磁环的径向充磁也较困难．基于这些原因，有时多采用若干个相同的 Passive magnetic bearings (permanent magnet bearings) of the permanent magnet ring are often used in two ways of magnetization, namely, radial magnetization and axial magnetization. For radial magnetized passive magnetic bearings, to achieve a strong radial radial magnetic field is more difficult, so to complete the high magnetic energy index, the larger the overall permanent magnet ring radial magnetization is more difficult. For these reasons, sometimes more to use a number of the same
