The aim of this study is to contribute at the characterization of vibration behavior in a five-phase flux switching machine permanent magnet (FSPM) under interturn short-circuit conditions. In this article, the vibration signature is obtained by experimental tests under both healthy and insulation failure conditions at 2100 rpm rotational speed. To extend the comprehension of short-circuit fault behavior, a previously implemented multiphysics model is adapted to studied cases. By a Finite Element Analysis (FEA)-based model, the radial component of magnetic induction in the airgap is calculated. The magnetic model is coupled to analytical mechanical model to determinate the displacement of inner circumference stator points. Following validation, this model is employed to study several configurations of short-circuit fault and the detection and discrimination of short circuit fault are discussed. Finally, an analysis of limitations and improvements of model is proposed.
