Dynamic modeling for PMSM with internal turn short fault

Abstract

If the stator winding of a permanent magnet synchronous motor (PMSM) has an internal turn winding fault, the symmetries in inductance and back emf collapse. As a result, negative sequence current is generated. The faulted PMSM dynamics are derived from a deformed flux model. The dynamics are developed in positive and negative sequence synchronous frames… (More)
