由于特殊的转子构型，可以将永久磁铁（PM）激发段转子通量开关机（SRFSM）的线圈通量连接视为每个相邻PMS产生的通量链接的总和。然后，通过通过场绕组在每个极对中替换一个PM以获得高磁场调节能力来获得混合激发SRFSM。首先讨论配置和操作原理。为了减少计算时间，开发了使用子域方法的混合激发SRFSM的分析模型。使用分析模型研究了电磁性能，例如通量连锁，后部电磁力，电磁扭矩和涡流损耗。此外，还分析了机器参数对扭矩波纹和平均扭矩的影响，以及场电流密度对通量弱化功能的影响。通过有限元方法和原型机器实验验证了分析结果。
Due to the special rotor configuration, the coil flux linkage of permanent magnet (PM) excited segmental rotor flux switching machine (SRFSM) can be considered as the sum of the flux linkages produced by each of the adjacent PMs. Then, the hybrid excited SRFSM is obtained by replacing one PM in every pole pair by field winding to obtain high magnetic field regulation capacity. The configuration and operational principles are first discussed. To reduce the computation time, the analytical model of hybrid excited SRFSM with the subdomain method is developed. The electromagnetic performances such as the flux linkage, back electromotive force, electromagnetic torque, and eddy current loss in PM and rotor support are investigated using the analytical model. Furthermore, the effect of machine parameters on the torque ripple and average torque, and the effect of field current density on the flux weakening capability are also analyzed. The analytical results are verified by the finite-element method and prototype machine experiments.
