The magnetic design of switched reluctance (SR) motors is inherently a hierarchical process. The design cycle progresses through distinct stages where the accuracy improves but computing times increase greatly, thus it often becomes impractical to furnish extensive multi-objective optimisation required to accomplish the optimal design. In order to enable rapid and accurate optimisation of SR motors, an improved reduced-order computational method of flux tubes is implemented to complement and practically replace the time-consuming 2D finite-element-based magnetic analysis. This study demonstrates how the use of the improved flux tubes approach to evaluate objective functions results in substantially faster while still accurate multi-objective optimisation of SR motors.
