Abstract

In order to enhance the torque output capability of Switched Reluctance Motors (SRM), this paper proposes two types of axial-radial mixed magnetic flux SRM topological structures with wide-narrow pole and same-tooth pole by combining the respective advantages of axial and radial magnetic fluxes. Two identically shaped axial stator structures are used, distributed on both sides of the rotor, forming an axial magnetic flux path with the central rotor. Simultaneously, on the outer side of the rotor, a radial stator structure is distributed, sharing the rotor to form a radial magnetic flux path. By using equivalent magnetic circuit analysis methods analyzing the flux linkage characteristic in a special position of the two topological structures, the superior torque performance of the axial-radial mixed magnetic flux SRM topology is determined. A prototype is manufactured and experimental verification is conducted.
