Stator Temperature Analysis of Turbogenerator in Rotor Inter-Turn Short Circuit
2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021The impact of rotor interturn short circuit (RISC) on the stator core loss and temperature is studied in this work. Different from existing research, this work is based on the variation analysis of the magnetic flux density (MFD) and the stator core loss calculation.

Diagnosis of stator inter-turn short circuits in DTC induction motor drives
38th IAS Annual Meeting on Conference Record of the Industry Applications Conference, 2003., 2004This paper addresses the subject of stator fault diagnosis in direct torque control (DTC) induction motor drives. The particularities of the behavior of a DTC drive, when in the presence of inter-turn short circuits, are exploited, thus allowing the proposal of two different approaches for the diagnosis of this type of fault.

Modeling and characterizing the inter-turn short circuit fault in PMSM
2011 IEEE International Electric Machines & Drives Conference (IEMDC), 2011In this paper, a dynamic model for PMSM with inter-turn fault is presented. FEM analysis is used for study the PMSM with inter-turn fault. Two methods for analytical calculation of parameters are presented. The first method widely used in literature computes the faulty inductances by applying a simple percentage on the parameters of healthy machine ...
