Analysis, dimensional sizing and configuration comparison of switched-reluctance motors operating under multiphase excitation

The paper presents a simple approach for analyzing switched reluctance motors (SRMs) operating under multiphase excitation. The analysis results in specific design coefficients [derived from the SRM flux and magnetomotive force (MMF) distributions that can be used in a methodology] to calculate the SRMs initial dimensions while taking into account the magnetic loading and electric loading. Finally, the approach enables comparison of SRM configurations for an application without performing complete designs. The magnetic loading (i.e., saturation) and torque of various SRM configurations designed using the proposed approach are verified through finite-element analysis (FEA).
