摘　　要：介绍了利用磁通法进行混合型永久磁铁的设计方法,相比传统的利用磁路的设计方法要精确了很多。结合加速器磁铁的设计原理,利用辐向磁化以及轴向永磁体和高磁导率铁钴钒极头对磁场的收拢作用,设计和制造出场强高于2.4 T的混合型永久磁铁。借助二维及三维磁场设计程序的计算和优化,可以设计制造出场强高且均匀度更好的永久磁铁。利用永久磁铁所产生的强磁场,可使磁铁的制造运行费用低,它们在加速器磁铁、材料科学研究、永磁电机、核磁共振成像技术中具有广阔的应用前景。This paper presented the method of designing the hybrid permanent magnet by using magnetic flux method, which was more precise than the traditional method of using magnetic circuit. In combination with the design principle for the accelerator magnet, a hybrid permanent magnet with the peak field of 2.4 T in the magnet gap was used by the radially and axially magnetized permanent rings. With the aid of the 2D and 3D software, the magnetic field was optimized, and thence a high strength and more homogenously hybrid permanent magnet was designed and fabricated. The high magnetic field produced by permanent magnet would find wide applications in the accelerator magnet, material science research, permanent motor and MRI, etc.
