摘要
Halbach磁体结构应用于电动机时与常规磁体结构相比具有很大的优越性,首先给出Halbach磁体结构电动机的磁体排列方式及磁体的磁化规律,然后以无齿槽有铁心电动机为例,对比分析Halbach磁体结构电动机和常规磁体结构电动机气隙磁密分布和电动机各部分磁通的差异,得出两种磁体结构电动机气隙磁密、磁通随永磁体厚度的变化规律。
Halbach array permanent magnet machine offers a number of attractive features in comparison with the normal array one. The structure and magnetized distribution of Halbach array when used in electric machines are presented. Take the example for slotless machine, the Halbach array permanent magnet machine is studied compared with the normal array one, the relationship between the air-gap field distribution and the magnet radial dimension is analyzed for different array permanent magnet machines.
