Halbach type permanent magnet track
The invention relates to the technical field of magnetic levitation, in particular to a Halbach type permanent magnet track. The permanent magnet track comprises two magnetism gathering yokes arrangedover a bottom plate and a permanent magnet array tightly arranged between the two magnetism gathering yokes. The permanent magnet array comprises N permanent magnets, the magnetization direction of the first permanent magnet is the horizontal direction, the magnetization direction of the first permanent magnet is the same as that of the last permanent magnet, and the magnetization direction of each permanent magnet anticlockwise rotates by an angle theta relative to the previous permanent magnet from the second permanent magnet. According to the permanent magnet track in the invention, the magnetization angle of a permanent magnet in an existing double-peak type permanent magnet track is optimized; the width-to-height ratio of the permanent magnet is reasonably configured, a ferromagneticmaterial with high magnetic conductivity is adopted as an iron yoke for fixing the permanent magnet, the magnetism gathering effect of the permanent magnet track is further improved, and a stronger magnetic field is generated above the track under the condition of the same track sectional area and the same permanent magnet using amount.
本发明专利涉及磁悬浮技术领域，尤其涉及一种Halbach型永磁轨道。包括设置在底板上方的两个聚磁铁轭和两个聚磁铁轭之间紧密排列的永磁体阵列，所述永磁体阵列包括N个永磁体，第一块永磁体的磁化方向为水平方向，第一块永磁体和最后一块永磁体的磁化方向相同，且从第二块永磁体开始，每块永磁体的磁化方向均相对于前一块永磁体逆时针旋转θ角。本发明中的永磁轨道，通过优化现有双峰型永磁轨道中永磁体的磁化角，合理配置永磁体的宽高比，并采用磁导率较高的铁磁性材料作为固定永磁体的铁轭，进一步提高永磁轨道的聚磁作用，在相同的轨道截面积与永磁用量的情况下，在轨道上方产生更强的磁场。
