Abstract :
This paper presents a novel 6/5 segmental rotor type switched reluctance motor (SRM) for cooling fan application. Different from conventional structures, the proposed structure of rotor consists of a series of discrete segments, and the stator is constructed from two types of stator poles: exciting and auxiliary poles. Furthermore, 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 a high efficiency. To verify the proposed structure, finite element method (FEM) is employed to get static and dynamic characteristics. Meanwhile, conventional 12/8 SRM is also analyzed for comparison.
