“…The main challenge in EV is high cost and low mileage, these two key factors are primarily dependent on the electric motor (e-motor) 7,8 . The main challenges to design motor is improving high power and torque density, high efficiency at low speed to achieve better performance for EV 9 . 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 10 .…”

The growth of Electric Vehicles (EV) moving towards to go green in the world. The high cost of EVs mainly depends on an electric motor. The Switched Reluctance Motor (SRM) speed-torque characteristics are perfectly suited for EV drive. Compared to other poly-phase machines, the SRM has high performance, magnet less, fault-tolerant, and high durability. The design has been carried out on electric vehicle grade modelling with different super core materials. This paper proposes the rating of 3kW, 3500rpm, and 8/6 topology by selecting stator and rotor optimal geometric parameters to design an efficient SRM configuration. The design step analyses the flux distribution uniform materials to analyze the performance of flux density, power, torque density, losses, efficiency, and torque ripple analysis. The finite element analysis is comparatively selected to improve the accuracy of material simulation for EV-SRM using Ansys Maxwell software to optimize the design for weight reduction, changing induction to reduce the acoustic noise.
