| 摘 要： | 利用POISCR程序计算了调变磁化方向型(MMD)和调变宽度型(MW)永磁多极磁体的磁场分布。本文对计算结果进行了分析。结果表明,考虑到永磁材料实际退磁曲线的非线性,两种型式永磁多极磁体所产生的磁场分布相似,而带软铁屏蔽的MW型磁体的场强略高于MMD型磁体。

| Abstract: | The field distributions of MMD type and MW type multipole permanentmagnets are calculated by means of programme POISCR and the results aresummarized and discussed in this paper. The results show that, considering thenonlinearity of the real demagnetization curve of permanent magnet material, thefield distributions of both types of permanent magnets with the same aperatureare about the same but the field strength of MW type magnet with soft ironshield is higher than that of MMD type magnet. |
