Design and characteristic analysis of a novel axial field SRM with single teeth stator and segmental rotor

A novel axial field disk type switched reluctance motor (AF-SRM) with single teeth stator and segmental rotor is introduced in this paper. The proposed stator poles are composed of excitation poles and auxiliary poles, the rotor is made up of a series of discrete segments. Because of the axial field structure and novel excitation source, the proposed motor can provide much higher output torque within reducing the copper loss. The basic design concepts are introduced and in order to calculate the characteristics of the proposed structure detailed, the finite element model is established base on the software of Maxwell 12-3D and Matlab/Simulink. Compared with the conventional 12/8 SRM in the same parameters, the proposed motor can provide higher output torque and more efficient, which is much suitable for the low speed and high torque application.
