Analysis of NVH Behavior of Synchronous Reluctance Machine for EV Applications

In this paper, an analysis of noise and vibration a synchronous reluctance machine for EV applications is performed. The analyzed was designed electric vehicle application. were first estimated during simulations; next, the obtained results validated laboratory tests. model simplified included only stator core as it assumed to be main source generated noise. To simulate machine, multiphysics modeling Laboratory tests proved correctness performed simulations. allowed us investigate influence machine’s operating point on vibration. frequency magnetic radial forces proven dominant factor in generation. load current angle negligible. It also that considering structure numerical leads valuable results.
