“…Most studies present the measurement results for experimental test stands with rotors specially prepared to damage the bars in the outer and inner cages [13,16,17,24]. Electrical and mechanical quantities were measured and analysed for transient start up [15][16][17] and steadystates operations [18,24,25,28]. These results allow us to recognise the effects of cage damages and suggest algorithms for rotor diagnostics.…”

This study presents a method to directly calculate the stator current Fourier spectra in double-cage induction motors to diagnose faults in rotor cages. A circuit model is developed for this purpose, allowing the modelling of any asymmetry in the outer and inner rotor cages. The model extends the conventional model of a cage motor by considering the higher space harmonics generated by the stator windings. The asymmetry of the cages is modelled by growing the resistance of any of the rotor bars. This results in various model equations, to be solved by looking for diagnostic signals. Motor current signature analysis is typically used to diagnose cage motors based on the Fourier spectra of the stator currents during steady-state operation. This study determines these spectra for double cage motors using the harmonic balance method, omitting the transient calculations. The calculation results confirmed the sensitivity of the stator current Fourier spectra as a diagnostic signal to distinguish faults in the outer and inner cages.

“…It is obvious from the findings that detailed work on the effect of static eccentricity on synchronous reluctance motor performance has not been explored. But enormous publications on eccentricity fault detection and modelling of induction machines have been recorded [37]. The majority of the researchers who attempted to investigate the synchronous reluctance machine stopped at finding the effect of eccentricity fault on the inductances using the WEM while others employed the stator current spectrum as the performance indicator to characterized and find the types and effects of rotor eccentricity fault on the machine.…”

Fault diagnosis and condition monitoring of synchronous machines running under load is a key determinant of their lifespan and performance. Faults such as broken rotor bars, bent shafts and bearing issues lead to eccentricity faults. These faults if not monitored may lead to repair, replacement and unforeseen loss of income. Researchers who attempted to investigate this kind of machine stopped at characterizing and deduced ways, types and effects of rotor eccentricity fault on the machine inductances using the winding function method. A modified closed-form analytical model of an eccentric synchronus reluctance motor (SynRM) is developed here taking into cognizance the machine dimensions and winding distribution for the cases of a healthy and unhealthy SynRM. This paper reports the study the SynRM under static rotor eccentricity using the developed analytical model and firming up the model with finite element method (FEM) solutions. These methods are beneficial as they investigated and presented the influence of the degrees of static eccentricity on the machine performance indicators such as speed, torque and the stator
