Effect of Stator Insulation Failure on the Motor Drive System Performance
Keywords:Fault detection, induction machine, inter-turn short-circuit, inverter-fed IM, FEA co-simulation
This study investigates the influence of the stator’s turnto- turn failures (TTFs) on the electromagnetic (EM) fields, such as air gap flux density, flux density in the stator, and rotor iron core inside of direct self-control (DSC) driven induction machines (IMs). The purpose of the investigation is to capture the fault signatures in the air gap EM flux for detecting the stator’s fault at its embryonic stage.
