Abstract

Currently, it is widely accepted that CO2 emissions are required to reduce significantly in order to keep global warming under control. This has led to rapid development of renewable energy and sustainable technologies. In automotive industry, hybrid and pure electric vehicles are most popular for the customer vehicles. The main part of these vehicles is traction drive. An electric machines with reduced magnet mass or with no magnets are of extremely attractive. Due to the development in power electronics, the switched reluctance motors (SRM) have gained popularity as a good candidate for the application of electric vehicle. In this paper, the performance comparison a 3-phase 12/8 and a 6/4 switched reluctance machines have been studied through finite element analysis by using Infolytica Magnet software. The simulation results shows that, as the higher number of stator and rotor poles the smaller change in geometry of the stator and rotor lead to improved magnetic characteristics and the energy efficient in torque production. The SRMs are proven to be able to replace the permanent magnet synchronous machine (PMSM for hybrid and pure electric vehicles.
