New methodology in sizing and predesign of switched reluctance machines using normalized flux-linkage diagram

This paper presents a new method in sizing and determining a preliminary design solution of switched reluctance machines (SRM). This proposed method is developed based on normalized flux-linkage curves of a generalized SRM model. Derived from the normalized flux-linkage curves, relationships between torque output curves, design parameters and machine configurations are represented in different intuitive graphical diagrams. Using the proposed method, designers can achieve better insights and comprehensive guides for SRM design in comparison to the existing methods. Hence, an appropriate initial preliminary design, minimizing time-expense in further optimization stages, can be systematically determined with ease.
