Abstract In this paper, a novel 6/13 electrical excitation flux-switching (EEFS) machine is proposed. The motor topology and operation mode, flux-switching principle of the EEFS machine were analyzed. Its electromagnetic performance, viz. the phase flux linkage and back electromotive force (EMF), magnetic field regulating ability, and the output property, were compared with electrical excitation doubly-salient (EEDS) machine based on finite element analysis. In different conditions, the output propetise of the EEFS machine and EEDS machine are compared especially. Besides, their copper loss and iron loss are compared. The results verify that the EEFS machine has good sinusoidal bipolar flux linkage and back electromotive force. In the same excitation condition, the EEFS machine has higher no-load EMF than the EEDS machine. Moreover, while providing the same voltage and current, the EEFS machine produces less copper loss and iron loss than the EEDS machine. Therefore the EEFS machine has higher efficiency than the EEDS machine.
