Abstract :

Design and optimization of high-power electric machines for the use of electric vehicles is one of the important issues today for the development of green technologies. Engines required for electric vehicles must have a power of more than 50 kW and must also produce torques of more than 200 Nm. The motors currently most commonly used in electric vehicle propulsion are permanent magnet synchronous machines. Due to the many problems of using permanent magnets in electric machines, the use of non-magnet electric machines such as switched reluctance machines have received much attention. Double stator switched reluctance machine is one of the newest types of these machines. Recently, another new type of electric machine called induction switched reluctance machine has been introduced for the use of electric vehicles. In this machine, the rotor conductors act like a magnetic shield by deflecting the magnetic flux, preventing magnetic field lines from passing through the rotor body. In this paper, a double-stator switched reluctance machine and an induction switched reluctance machine are considered and their properties are extracted by finite element method. The simulation results including torque profile, torque density and efficiency are presented and compared. Finally, the best topology for electric propulsion is proposed.
