The analysis of airgap eccentricity in three-phase induction motors using finite elements for a reliable condition monitoring strategy. (1998)
Thesis
BARBOUR, A. 1998. The analysis of airgap eccentricity in three-phase induction motors using finite elements for a reliable condition monitoring strategy. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2807289

This thesis presents the results of a finite element investigation into airgap eccentricity in three phase induction motors. Airgap eccentricity is an inherent condition in induction motors which if left undetected can result in motor failure. It is...

The monitoring of induction motor starting transients with a view to early fault detection. (1992)
Thesis
ELDER, S. 1992. The monitoring of induction motor starting transients with a view to early fault detection. Robert Gordon University, PhD thesis.

The aim of this work is to investigate the possibility of detecting faults in a 3 phase Induction motor by monitoring and analysing the transient line current waveform during the starting period. This is a particularly onerous time for the machine an... Read More about The monitoring of induction motor starting transients with a view to early fault detection..

The work presented in this thesis is based on theoretical and experimental investigations into the changes in measurable squirrel cage induction machine parameters such as vibration, line current and leakage flux which alter during machine faults. In... Read More about Induction motor fault recognition..

Computational aspects of on-line machine monitoring. (1984)
Thesis
MILNE, A.J. 1984. Computational aspects of on-line machine monitoring. Robert Gordon's Institute of Technology, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1993208

The detection of the fault phenomena found on three phase induction motors, as widely used in industry, from an electrical engineering viewpoint has been investigated. Various transducers are used, on a real motor, to establish connections between kn... Read More about Computational aspects of on-line machine monitoring..
