Design and analysis of an axial and radial hybrid flux switched reluctance motor with identical poles for electric vehicles

To address the shortcomings of traditional switched reluctance motors in electric vehicle drive applications, such as large torque pulsation and low torque density, a novel axial radial flux segmented rotor switched reluctance motor (ARFSRSRM) for electric vehicles is proposed. First, the topology and working principle of the motor are introduced, followed by the derivation of design parameters based on the power equation. Next, four structural parameters are selected for optimization using orthogonal test matrix analysis through finite element methods. The optimal parameter combination is determined by combining the weight matrix of multi-objective influence factors to further enhance motor performance. Finally, the accuracy of the ARFSRSRM model and the effectiveness of the proposed motor structure on performance enhancement are verified by comparing simulation experiment and the static and dynamic characteristics analysis, respectively. © 2024 Power System Protection and Control Press.
