“…Some scholars also provide effective solutions for open‐circuit fault diagnosis of PMs and induction machines [15–17]. In [18], the change rule of the negative sequence current with degree and position is studied, which provides a theoretical basis for fault diagnosis of stator windings of PM wind turbines. In [19], the steady‐state and dynamic response of an interior PM (IPM) synchronous machine drive to a single‐phase open‐circuit fault is investigated.…”

As the core of the distributed generation system, the health status of high‐speed permanent magnet generator (HSPMG) has attracted much attention. HSPMG is often used in military, rescue and other fields. When the open‐circuit fault of HSPMG stator winding occurs, it will seriously affect the operation stability and power supply reliability. In this study, a 117 kW, 60,000 rpm HSPMG is taken as an example, and a 2D finite element model is established. The accuracy of the model is verified by comparing the calculated results with the experimental data. By the field‐circuit coupling method, the magnetic field changes pre‐and post‐fault is analysed, and the mechanism of magnetic field spatial distribution changes post‐fault is revealed. In addition, the changes in eddy current loss pre‐and post‐fault are analysed. The influence of the harmonic magnetic field and the rotating magnetic field produced by negative sequence current on eddy current loss is studied, and the dominant factors effecting eddy current loss post‐fault are investigated. The study provides some useful conclusions for HSPMG fault analysis.

“…Their root cause is largely in the combination of operating thermal, mechanical and electrical stress, and environmental factors related to the application in which these machines operate [5], [6]. Winding faults are generally defined as short circuit (SC) or open circuit (OC) faults; the latter can result from a SC fault but can also be initiated due to improper connection or excessive vibration [7], [8].…”

Detection of winding faults in permanent magnet synchronous machines (PMSMs) with stranded winding designs remains a challenging task for conventional diagnostic techniques. This paper proposes a new sensing approach to this problem by investigating the application of dedicated electrically non-conductive and electromagnetic interference immune fiber Bragg grating (FBG) temperature sensors embedded in PMSM windings to enable winding open-circuit fault diagnosis based on observing the fault thermal signature. The final element analysis thermal and electromagnetic models of the examined practical PMSM design are first developed and used to enable the understanding of open-circuit winding fault-induced signature that can be used for effective diagnostic purposes, indicating in situ thermal excitation as an optimal diagnostic measurand. A purpose build test rig with an inverter-driven commercial PMSM instrumented with in situ FBG sensors monitoring phase winding hot spots is then used to evaluate the efficacy of the proposed diagnostic scheme. It is shown that unambiguous diagnosis and severity trending of winding open-circuit faults is enabled by the use of in situ FBG sensors. A comparison with conventional fault diagnostic technique utilizing current signal sensing and analysis is also reported, indicating the considerable advantages of the proposed monitoring scheme employing FBG sensors.
