The switched reluctance machine (SRM) has seen a lot of interest due to its simplicity and ruggedness. Much attention have been paid in academia to improve on some of the disadvantages of the technology such as torque ripple, acoustic noise and low torque density. In this paper a topology, namely the double U-core SRM, is reviewed. This topology improves on some of the disadvantages of the regular SRM. Torque ripple is reduced and the torque density is increased for the same amount of material, by reconfiguring the topology of the regular SRM and increasing the number of poles. The result is a segmented stator structure where each segment can be wound individually and assembled afterwards. Several similar technologies have been demonstrated, and the claimed advantages have been proven in comparison with regular SRMs with a lower pole count. In this paper, the technology will be compared to a regular SRM with a similar pole count, to assess the advantages of the technology, when disregarding the increased number of poles. This paper therefore serves the purpose of proving and assessing the technology through a straightforward theoretical comparison of a regular and a double U-core SRM. From this comparison the claims of the technology can be proven and the gain from utilising the technology can be assessed objectively.
