Abstract
Vibration and acoustic noise limit the application of switched reluctance motors (SRMs). Because the radial vibration of the stator is the primary source of the acoustic noise of SRMs, the modal analysis of the stator vibration is an important and effective way to reduce the acoustic noise. In this paper, we construct eight computational models by varying the structural forms, height, quantity, and shape of radiating ribs to investigate the influence of radiating ribs on the mechanical resonant frequencies, under the condition of the same amount of radiating rib material. We apply three-dimensional finite-element modal analysis to accurately analyze these models. Finally, we derive an optimal structure of the radiating rib to lower the acoustic noise level of SRMs and dissipate heat.
