This paper presents a detailed analysis of short-circuit current behavior during interturn short-circuit faults in permanent magnet synchronous machines (PMSMs) by considering the short-circuit contact resistance. For this purpose, an finite element analysis (FEA)-based equivalent circuit model is developed to understand the circulating current behavior in the shorted turns. Various fault resistance and number of shorted turn combinations are examined at different torque and speed levels. To include saturation due to high fault currents, the inductance matrix of faulty machine is created in FEA environment and incorporated into the equivalent circuit model as four-dimensional lookup tables. In order to take loop responses into account, the model is controlled through field oriented control (FOC) with closed speed and current loops. An experimental setup is built to verify the simulation results using a PMSM with several winding taps. It is shown that the experimental results and the simulations are quite consistent with each other. The findings from this study are essential to predict fault severity, develop mitigation techniques and determine the safe operating area for faulty machines.

Interturn short-circuit faults in permanent magnet synchronous machines: An extended review and comprehensive analysis Zafarani, Mohsen; Bostancı, Emine; Qi, Yuan; GÖKTAŞ, TANER; Akin, Bilal (2018-12-01) This paper presents an extended review and recent advances in modeling and diagnosis of interturn short circuit (ITSC) faults in permanent magnet synchronous machines, supported with in-depth fault analysis. In the analysis part, the influence of the fault intensity on the machine's parameters and performance is analyzed at various operating conditions through finite-element analysis, drive system models, and test bench measurements. The presented findings shed light on the fault signatures and factors that...
Analysis and Fault Tolerant Control of a Five-Phase Axial Flux Permanent Magnet Synchronous Machine Bayazıt, Göksenin Hande; Keysan, Ozan; Department of Electrical and Electronics Engineering (2021-9-06) This study investigates the fault-tolerance capability of an air-cored, axial flux, five-phase permanent magnet synchronous machine. The air-cored stator is designed by adopting a novel winding topology that is called flat winding. The coils of flat winding are made by bending and grouping one within another of the flat wires made of a laser-cut thin aluminum sheet. This topology provides superior current ratings, better cooling performance, and a robust structure for the stator. As the coils are covered w...
A New Method for Leakage Inductance Calculation of Transverse Flux Machines Zafarani, Mohsen; Moallem, Mehdi; Ghadamyari, Mohammad Adib (2011-09-10) This paper presents a new analytical method for leakage inductance calculation of transverse flux permanent magnet machines. In this method, leakage flux paths are predicted base on the finite element results, and then all paths would be modeled by flux tubes. Finally, the inductance of the machine would be obtained by calculation of the permeance of flux tubes. The validity of the proposed model is verified by comparing the Finite Element results with the results obtained from the proposed approach. Compar...
Low-cost motor drive-embedded fault diagnosis a simple harmonic analyzer AKIN, Bilal; TOLIYAT, Hamid A.; Orguner, Umut; RAYNER, Mark (2007-03-01) The reference frame theory and its applications to fault diagnosis of electric machinery as a powerful tool to find the magnitude and phase quantities of fault signatures are explored in this paper. The core idea is to convert the associated fault signature to a dc quantity, followed by calculating the signal average value in the new reference frame to filter out the rest of the signal harmonics, i. e. its ac components. Broken rotor bar and rotor eccentricity faults are experimentally tested both offline u...
Line Current Analysis for Bearing fault Detection In Induction Motors Using Hilbert Transform Phase Oumaamar, M. E. K.; Razik, H.; Rezzoug, A.; Khezzar, A. (2011-09-10) The present paper focuses by means of an experimental study, on the effect of a bearing fault on the stator current signatures in induction motors. The variation in the amplitude of the characteristic components is not so significant. For that and in order to depict the presence of the fault harmonic signatures, the authors used the phase analysis of Hilbert transform applied on the spectrum modulus of the line current.
