Effect of Stator Insulation Failure on the Motor Drive System Performance

摘要

This study investigates the influence of the stator’s turnto-turn failures (TTFs) on the electromagnetic (EM) fields, suchas air gap flux density, flux density in the stator, and rotor ironcore inside of direct self-control (DSC) driven induction machines(IMs). The purpose of the investigation is to capture the faultsignatures in the air gap EM flux for detecting the stator’s fault atits embryonic stage
