To meet the high- performance requirements of new energy vehicle drive, the optimization design of 8/6 Switched Reluctance Motor is realized based on finite element parametric modeling of the motor. Firstly, the initial design of motor structure parameters is carried out based on the mathematical model of Switched Reluctance Motor, and the simulation model of the motor is built using RMxprt platform, and the debugging of the characteristics of the wide speed range of the motor is finished. Then, the parametric finite element model of the motor is generated, and the stator and rotor pole arc coefficients of the motor are selected as the optimization variables, and the multi-objective compromise optimization of the torque characteristics and efficiency of the motor is carried out by using the Quasi-Newton method weighting method. Finally, the magnetic field distribution, torque characteristics, efficiency and speed range characteristics before and after optimization are compared, proving that the optimized Switch Reluctance Motor can achieve multi-objective performance optimization. The motor designed by this modeling optimization method can improve the requirements of vehicle driving better.

“…The number of rotor poles, stator slots is matched with eight poles and 48 slots with the distributed windings aiming to reduce the fifth, seventh harmonics. When the IPMSM is running under continuous operation conditions, the larger the continuous phase current amplitude, the larger the corresponding current density and the higher temperature of the permanent magnet, which will lead to the decrease of the output torque of the IPMSM under the same magnitude of continuous phase current and increase the risk of irreversible demagnetization of the permanent magnet, so the amplitude of continuous phase FIGURE 1 The IPMSMs with different rotor topology structures.

“…Induction motor has mature manufacturing technology, higher reliability and strong environmental adaptability, but it has low efficiency and low torque density under urban working conditions. Switched reluctance motor is also a potential electric vehicle (EV) drive motor, which is a reliable motor under different environmental conditions, has the advantages of relatively simple structure, high reliability, no permanent magnet, low cost and has the disadvantages of large torque ripple [1][2][3].…”

Switched Reluctance Machine (SRM) is the advanced version of the stepper motor and since last decade, it is of high interest among researchers and industrial applications. Modelling an SRM relies on accurate data and proper selection of parameters. The next step is the performance analysis of the machine for which losses determination is indispensable. Previous studies have shown losses calculation only at a particular instant of switching of the machine (i.e., conduction angle). Therefore, the impact of losses in a motoring region cannot be justified. This paper investigates the impact of varying conduction angle on the performance of machines for a set of switch-on angle. Losses are calculated and predicted through simulating motor operating parameters carried out in MATLAB environment and accuracy of results are compared with experimental results.
