Electromagnetic Diagnostics of Stator Inter-Turn Short Circuits in a 8-Pole PMSM

appNote
This application note presents a finite element–based electromagnetic analysis of stator inter-turn short-circuit faults in an 8-pole PMSM. It demonstrates how localized electrical faults induce global electromagnetic coupling effects that impact key motor parameters—such as current distribution, magnetic flux, and torque production—highlighting the need to model inter-turn short-circuit faults as magnetic failures for more accurate diagnosis.
