85A novel designing approach to dual rotor switched reluctance motor based electric vehicles

Electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. The critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. Switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gear transmission. Recently developed dual magnetic circuit reluctance machine configuration make it added advantage with its feasibility on the optimizing the magnetic flux flow. The dual magnetic circuit reluctance machines through double rotor is presented and compared with conventional machine for its power density. Further to evaluate the dynamic performance the proposed machine is compared with that of the conventional machine. It is found that the torque density of the proposed machine is 65% higher than that of the conventional machine and show promising candidate for the EV and HEV applications in the near future.
