Sustainable Electric Motor Development for Electric Vehicle

Abhishek Kumar Singh

Abstract


The SRMs are gaining much interest and are recognized to have a potential for hybrid electric vehicle (HEV) applications because of its several advantages. There are, however, several disadvantages, which for many applications outweigh the advantage. The torque ripple, acoustic noise and speed ripple. The highly non-linear nature of the SRM operating in saturation makes analytical modelling extremely difficult. The main aim of this project is to employ the nonlinear controller for switched reluctance motor to reduce the torque and speed ripple to make it suitable for HEV. The proposal of the switched reluctance motor for hybrid electric vehicle is simulated by using MATLAB Simulink model. All the electric vehicles (EVs) invariably use an electric motor to drive the wheels from the stored energy in a battery. The selection of the type of electric motor, control circuit hardware and matching it with the battery bank supply decides the performance of the overall EV. This paper discusses the need to select the correct electric motor to meet all the functional requirements of the EV customer. The sustainable development of electric motors should mandate the matching with the latest battery technology preferably recharging through a renewable source of energy, power electronics and microcontroller-based control unit. In addition, what needs to be considered in the development of sustainable next generation electric motors is that they should use very less amounts of rare earths (or avoid magnets) for the commercial viability and raw material availability. This approach is significantly different from the earlier focus on efficiency driven design and utilizing the motor torque-speed characteristic to optimize the EV performance. The guidelines in the electric motor development should lead in designing the EV which will sustain in the automotive market.
