Design, Simulation, and Analysis of Switched Reluctance Motor for High-Speed Applications

High-speed motors are becoming popular, especially in traction applications. In traction applications, reductions in weight and size are of utmost importance due to stringent space constraints. With high speed, power density increases, thereby reducing the size and weight of the motor while making the design more cost-effective. Permanent Magnet (PM) motors dominate the transportation sector for several decades. But cost and supply chain issues associated with PM materials push researchers to opt for alternate motor drive technologies Switched Reluctance Motor (SRM) is widely adopted in high speed applications. The simple and robust structure of the SRM makes them a viable solution where high speed is required. In this paper, a detailed stepwise design procedure to design an SRM is presented. Expressing the output equation in terms of the motor's back emf and the saliency ratio and considering the mechanical constraints, the design procedure is proposed. In the literature design methods of SRM is categorized as the linear method, non-linear method, and finite element method (FEM).FEM is the most accurate and widely adopted method with the advancement of commercial FEA software. In this work, a 6/4 SRM is considered. The analytical approach is used to perform the initial calculations to obtain the motor parameters then Ansys RMxprt is used to validate the proposed design. Further electromagnetic analysis is carried out using Ansys Maxwell. Characteristics of the motor are plotted in terms of waveforms, and the performance prediction is reported. Finally, the total loss incurred during the operation is presented.
