This paper presents a novel modular switched reluctance machine (SRM) with E-core stators and segmental rotors for electric vehicles. Unlike the conventional SRMs, there are both radial and axial fluxes in the E-core stators due to the particular construction. To evaluate the motor performance, a simplified 2D model and 3D model finite-element analysis (FEA) are utilized to calculate its magnetic characteristics. A comparative study between the modular SRM and a conventional SRM is made. Furthermore, the fault tolerant performances of this modular SRM under open-circuit faults are also predicted. Finally, a prototype machine is fabricated and tested. The flux linkage characteristics are experimentally obtained to compare with FEA results. More experimental results such as single-pulse operation, closed-loop control operation, fault-tolerant operation at open-circuits and sudden change in load torque operation are also presented to validate the analysis and simulation of the modular SRM and its performance.
