High torque double-stator switched reluctance machine for electric vehicle propulsion

In this paper a high torque double-stator switched reluctance machine (DSSRM) is proposed for electric vehicle propulsion. DSSRM is a novel variable reluctance synchronous machine with two stators and one rotor. The magneto-motive force (mmf) orientation of these coils in DSSRM is such that a short flux path is created. To compare torque per mass of a DSSRM with that of a conventional SRM, finite element models are constructed. An experimental prototype of the proposed machine is developed and the static torque is measured. The results of our investigations indicate that the proposed geometry offers superior performance in terms of higher torque per mass.
