摘　　要：分析了一种用平行与径向的混合磁化方式。采用三维有限元方法,得出混合磁化下,不同剩磁比以及不同极弧系数比时,永磁无刷电机的气隙磁密、反电势以及齿槽转矩等参数。计算结果表明,与单一磁化相比,混合磁化能够优化和提高电机性能。对永磁无刷电机的结构优化具有参考价值。A mixed magnetization with parallel and radial magnetization was presented. The no-load magnetic field parameters of a permanent magnet brushless motor with mixed magnetization have been obtained by a three dimensional finite element method, including the air gap flux density, back EMF and cogging torque. The computation results show that the mixed magnetization motor can improve the performance compared with the unique magnetization. The results are helpful for optimization of the permanent magnet brushless motor.
