A Novel Approach to the Design and Development of a C-Core Sandwich-Type Radial Field Switched Reluctance Motor with On-Shaft Implementation in EV Application

A novel design for a radial field switching reluctance motor with a sandwich-type C-core architecture is proposed. This approach combines elements of both traditional axial and radial field distribution techniques. This motor, similar to an in-wheel construction, is mounted on a shared shaft and is simple to operate and maintain. The rotor is positioned between the two stators in this configuration. The cores and poles of the two stators are separated from one another both magnetically and electrically. Both stators can work together or separately to produce the necessary torque. This adds novelty and improves the design’s suitability for use with electrical vehicles (EVs). A good, broad, and adaptable torque profile is provided by this setup at a modest excitation current. This work presents the entire C-core radial field switched reluctance motor (SRM) design process, including the computation of motor parameters through computer-aided design (CAD). The CAD outputs are verified via finite element (FE) analysis.
