The machine was designed and the flux regulation characteristics were evaluated. By adding a low coercive force (LCF) PM, whose magnetization state can be varied by magnetization control pulse current, to a high coercive force (HCF) PM, high air-gap flux density as well as direct flux regulation can be realized. The influences of PM ratio on the magnet flux density and the flux regulating factor were investigated by the 3D finite element analysis (3D-FEA). The magnetic field distribution of the series PMs and the corresponding electromagnetic performance under different magnetization states were comprehensively investigated. Based on the previous analysis, a prototype was manufactured and tested. The measurements validate the correctness of the simulation results. It is proved that a continuous and smooth flux control capability is obtained by varying the magnetization states of the LCF PM through pulse current. The copper loss produced by magnetization control pulse current is negligible and thus the machine efficiency in the high speed region is improved. The solution enables flux controllability in the flux-switching machine and is very suitable for electric vehicles where the wide-speed operation and high efficiency are required.
