This study investigates the effect of different skewing methods and angles for switched reluctance machines (SRM) having high pole count using multiphysics simulations. A 24/16 SRM is modeled for each skewing method and different skewing angles using 3D electromagnetic finite element analysis (FEA). Mechanical and acoustical analyses are performed to evaluate the effectiveness of different skewing...
High vibration and acoustic noise are known to be the most dominant disadvantages for utilizing SRMs in Hybrid electric vehicles or home appliance applications. One of the methods for mitigating these disadvantages is to introduce windows in the SRM structure to reduce the magnitude of the radial force responsible for stator deformation. Previous studies are focused on introducing windows in the rotor...
This paper presents a distributed airgap in the stator of switched reluctance machines (SRMs) to reduce the vibration and the acoustic noise levels. Distributed airgap is placed in stator tooth or yoke to analyze its effectiveness on the electromagnetic and mechanical performances. According to the observations, it has been found that when the distributed airgap is placed in the stator teeth, the...
