A novel 6/5 segmental rotor type switched reluctance motor: Concept, design and analysis

A novel 6/5 segmental rotor type switched reluctance motor (SRM) is proposed in this paper. Different from conventional structures, the rotor of proposed structure is constructed from a series of discrete segments, and the stator is constructed from two types of stator poles: exciting and auxiliary poles. Moreover, in this structure short flux paths are taken and no flux reversion exists in the stator. Compared with conventional SRM, the proposed structure increases the electrical utilization of the machine and reduces the core losses, which may leads to higher efficiency. To verify the proposed structure, finite element method (FEM) is employed to get static and dynamic characteristics of conventional 12/8 and proposed SRM. Finally, the validity of the proposed structure is verified by the analyzing results.
