Abstract: Structural Finite Element Analysis is used to investigate potential improvements in the design of low vibration, doubly salient switched reluctance motors (SRMs). The natural modes of vibration of a 4-pole round-stator are examined. The dynamic response of the machine stator when electromagnetic forces are applied at the stator poles is fully examined in this paper. The 4-pole, round-stator SRM is compared with a common square-stator motor as well as a novel square-stator structure, in which the poles are positioned at the square corners. Other machine design cues aimed at reducing vibration, such as the addition of pole fillets and the choice of suitable back iron width, are investigated.
