Spatial distribution of acoustic noise caused by radial vibration in switched reluctance motors: Application to design and control Conference Paper

abstract

• A magneto-acoustic approach for calculation of acoustic field caused by radial vibration of the stator is proposed. In the first step, using a 2-D finite element (FE) method along with a dynamic model of the Switched Reluctance Motor (SRM) drive, radial forces acting on the stator poles are calculated. Further, stator deformation due to the radial forces is computed using a time stepping FE analysis. This structural information is then fed into another FE based fluid- simulator, which predicts the acoustic field at any point in the surrounding space. Further, the impact of current profile on the emitted noise is analyzed.
