The driving motor of an electric vehicle should satisfy its specific requirements of both starting
and providing an extended speed range at constant power within operating constraints (e.g.
acceleration and gradeability). This paper investigates the capability of the switched reluctance
motor (SRM) for electric vehicle (EV) applications by introducing a suitable controller. The
proposed controller uses a fixed as well as an adapted switching angles control schemes to
maximize the machine overload capability. Both Turn-on angle and conduction angle have great
influence on developed torque and they can be chosen to maximize the operating speed range and
hence extends the constant power region essentially required for EV. A nonlinear analysis for an
816 SRM is developed and implemented in a simulation program based on Matlab/Simulink
software package to investigate the motor dynamics. An experimentally measured flux linkage‌current and static torque arrays are used to represent the machine data for simulation. The
performance of SRM drive system with the proposed controller is introduced to study the effect of
the proposed control scheme on current, torque, speed response and also constant power region.
Motor currents and developed torques are obtained at different operating conditions and useful
conclusions are obtained
