Analysis of The Effect of Inductance and Rotor Position on the Performance of a Switched Reluctance Motor Using Geometry-Based Analytical Method

Abstract

This paper investigates the impact of inductance and rotor position on the performance of a 4-phase, 8/6 Switched Reluctance Motor (SRM) in electric drive systems. The study employs a geometry-based analytical model using Ansys-Maxwell software to investigate the inductance profile, which aids in identifying key torque regions, ensuring sound design and control optimization. To study the performance characteristics of a switched reluctance motor, the relationship between inductance and rotor position is vital, as it directly influences torque generation, efficiency, and dynamic response. The model provides a computationally efficient foundation for performance assessment and future enhancements using numerical methods. The results obtained show that while the inductance variation relative to rotor position drives torque production, saturation at high currents limits motor performance, therefore, the phase current need to be properly managed to ensure optimal performance.
