Stator Winding Monitoring

IEEE Industry Applications Magazine, 1998
Partial discharge tests can determine which motor and generator stator windings are experiencing insulation problems. A deteriorated winding has a PD activity which can be 30 times or more higher than a winding in good condition. This great difference in PD activity enables even nonspecialized maintenance personnel to identify the few motors or ...

Failure analysis of general stator and uniform wall thickness stator

Engineering Failure Analysis, 2018
Abstract Stator lining of positive displacement motor (PDM) is prone to generate thermal fatigue failure because of viscoelastic hysteresis of the rubber material. Based on the thermo-mechanical coupling modeling and rubber material testing, finite element method was used to study the effect of environment temperature and thermo-viscoelastic ...

Stator Winding Fault

2016
The chapter deals with stator winding faults. Assessments of different types of stator winding fault are discussed in this chapter. Both steady-state and transient current-based diagnosis are covered. Sequence component-based stator fault diagnosis is presented. Park plane is sometime used for fault diagnosis.

Partitioned Stator Flux Reversal Machine With Consequent-Pole PM Stator

IEEE Transactions on Energy Conversion, 2015
In this paper, partitioned stator flux reversal permanent magnet (PS-FRPM) machines having different stator/rotor pole combinations with consequent-pole PM (CPM) stator are proposed and analyzed. Compared with the conventional 12-stator-pole PS-FRPM machines having 10-, 11-, 13-, and 14-rotor-pole rotors and surface-mounted PM (SPM) stator, the PM ...

Time-Space Spectral Method for Rotor–Rotor/Stator–Stator Interactions

Journal of Turbomachinery, 2019
AbstractThe paper presents a time-space spectral method for an efficient analysis of rotor–rotor/stator–stator interactions in the framework of the time spectral form harmonic balance method. The method treats time and space harmonics in a coherent way and allows for easy choice of time and passage through the introduction of pseudo-shaft frequency and

Novel salient inner stator Partitioned Stator Switched Flux PM machine

2016 Eighteenth International Middle East Power Systems Conference (MEPCON), 2016
A novel salient inner stator Partitioned Stator Switched Flux PM machine is proposed in this paper. The proposed machine combines the operation principles of the partitioned stators and the outer-rotor switched flux permanent magnet machine. It employs the rotor and stator of a partitioned stator switched flux machine as a rotor and an outer stator ...
