Design and analysis of a DC field multitooth switched reluctance machine by using soft-magnetic-composite material

This paper innovatively implements the dc field winding into the multitooth switched reluctance (MSR) structure to form a new DC field multitooth switched reluctance (DC-MSR) machine. The independent DC field winding can effectively achieve field excitation for efficiency optimization. Soft-magnetic-composite (SMC) material which is favorable for the complex structure is also applied into the proposed machine. In addition, the characteristics and performances of the proposed machine are analyzed by finite element method with various excitations.
