On-line diagnosis of inter-turn short circuit fault for DC brushed motor

ISA Transactions, 2018
Extensive research effort has been made in fault diagnosis of motors and related components such as winding and ball bearing. In this paper, a new concept of inter-turn short circuit fault for DC brushed motors is proposed to include the short circuit ratio and short circuit resistance.

Inter Turn Short Circuit Fault Analysis of Five-Phase PMSM

2021 IEEE 4th International Conference on Computing, Power and Communication Technologies (GUCON), 2021
Multiphase machines especially Five Phase Permanent Magnet Synchronous Motor (PMSM) have experienced continuous growth in recent times and are used in high power applications like ship propulsion, locomotive traction, aircraft, electric vehicles, etc., due to its less torque ripples, high fault tolerance, and robustness.

Inter turn short-circuit fault research on generator rotor windings

ICEMS'2001. Proceedings of the Fifth International Conference on Electrical Machines and Systems (IEEE Cat. No.01EX501), 2002
Based on the fault characteristics, where the exciting current increases and the output reactive power reduces, when an inter turn short-circuit occurs in rotor windings, and considering the saturated situation of generator, a fault characteristic mathematical model of inter turn short-circuits on generator rotor windings is founded.

On-line inter-turn short-circuit detection in permanent magnet synchronous generators

2013 9th IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives (SDEMPED), 2013
This paper focus on inter-turn short-circuit detection in Permanent Magnet Synchronous Generators (PMSG). Inter-turn short-circuit current are among the most critical in the PMSG. For safety considerations, a fast detection is required when a fault occurs. In this work, a fault indicator for on-line diagnosis is proposed.

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., 2004
This 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.

Stator Temperature Analysis of Turbogenerator in Rotor Inter-Turn Short Circuit

2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021
The 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.

Experimental inter-turn short circuit fault characterization of wound rotor induction machines

2010 IEEE International Symposium on Industrial Electronics, 2010
The aim of this paper is to compare different experimental techniques for detecting a stator inter-turn short-circuit in a Wound rotor induction machine working as generator. Three methods using different signals such as stator or rotor current and the leakage flux will be described and experimented.

Inter-turn short-circuit fault model for magnetically coupled circuits: A general study

2016 IEEE Industry Applications Society Annual Meeting, 2016
Inter-turn short-circuit (ITSC) fault is one of the most typical fault in different types of magnetically coupled circuits such as transformers and rotating or linear electrical machines. This paper presents a general study to approach the ITSC understanding and modeling as long as the circuit can be represented in state-space (SS) equations.

Modeling and characterizing the inter-turn short circuit fault in PMSM

2011 IEEE International Electric Machines & Drives Conference (IEMDC), 2011
In 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 ...
