Battery powered 4-phase 8/6 pole SRM drive for advanced electric vehicle

摘要

A growing need for “electric vehicles” against fuel consumption and pollution is seen all around the world. Unlike vehicles with combustion engines, battery powered electric vehicles do not produce exhaust gases during operation. There is no fuel odor and these vehicles are silent. These features itself makes battery powered electric vehicles more environment friendly than vehicles with conventional technologies. Switched Reluctance Motor (SRM) has gained its importance in variable speed control operations as it has advantages like constructional simplicity, high starting torque, no magnets or windings on the rotor and adaptability to hostile conditions. In this paper, a four phase SRM drive operated with hysteresis control is shown which can be used to drive an electric vehicle. Hysteresis control is used for low speed operations so that this simple control can be used in electric vehicles specially designed for metro purposes. MATLAB/SIMULINK simulation results are presented for this control strategy.
