A new Dual Stator-Dual Rotor Switched Reluctance Motor for Electric vehicle propulsion

Switched Reluctance drives are gaining importance as an alternative to Permanent magnet BLDC motors due to their low cost and simple construction. In this paper a new Dual stator-Dual rotor Switched reluctance motor(DS-DR SRM) is proposed which is competent to Permanent magnet Brushless DC motor (PM-BLDC) with high power density. Non-linear magnetic analysis on the machine is carried out using 2-D Finite element model and all the magnetic parameters and load characteristics of the machine are derived. The current-torque characteristics of the proposed topology is compared with conventional external rotor SRM and observed an increment of 30% in peak torque density. The proposed motor is best suitable for high Power density applications where non-permanent magnet machines are gaining importance like electrical vehicles
