A mathematical and FEM design of novel axial field switched reluctance motor for electrical vehicle (EV) application

Abstract

Switch reluctance (SR) motors attract attention as a motor that does not use permanent magnet material. So it is a strong candidate for electrical vehicle (EV) application. In EV application axial flux machines are preferred over radial flux machines due to high power density. In this Article novel axial field switched reluctance motor (AFSRM) design is presented which intend to improve the output torque by single flux path distribution in C- core stator. Unlike conventional radial field SRMs, the windings of the C-core stator can be individually wound without complex winding equipment. This topology has an 8/6 pole dual air gap single rotor and single C-core stator configuration without overlapping winding arrangement. Computer Aided Design (CAD) is used to calculate the phase inductance and average torque for a novel AFSRM topology. The two and three-dimensional Finite element (FE) analyses is carried out to validate obtained CAD results.
