Design and Development of High Performance 3kW Electric Vehicle Grade Switched Reluctance Motor

In modern era the automotive industry transformation to electrifying from internal combustion engine to electric vehicles (EVs). The shortage of fossil-based sources demands increasing the price and high emission of greenhouse gas emission transportation to shift go green. The EVs benefits big diversity in fuel portfolio, reduced dependence on fuel sources, energy independence, healthier environment and for smart cities. The new e-mobility models and emerging technologies helps to improve the EV in the market last two decades. The main challenge in EV is High cost and low mileage, these two key factors are primarily dependence on electric motor(e-motor) [1]. To achieve better EV performance and overcome the problems by improve higher power and torque density, increasing the efficiency are main challenge in advanced e-motor design. Often to attain these goals using non-permanent magnet material, constructing the stator and rotor out of minimum inductance, high permeability and low loss soft magnetic materials. The optimal performance of EV using low-cost material in e-motor design higher acceleration, increasing payload capacity, improving range and improving space savings [3]. At present e-motors are rare earth material permanent magnet synchronous motor has high efficiency and power density is suitable for EV powertrain with high cost. The non-magnet material induction motor has developed control techniques with low cost is suitable for EV powertrain with low efficiency and high core loss.
