On-line condition monitoring and detection of stator and rotor faults in induction motors.
… motor in order to determine the types of faults and their severity while the motor is under a normal operating condition. The work in this thesis investigates the detection of stator and rotor faults (i.e. shorted turn faults, eccentricity faults, and broken rotor bar faults) using three …

Detection of Rotor and Load Faults in BLDC Motors Operating Under Stationary and Non-Stationary Conditions
… of this research is to advance the field of rotor and load fault diagnosis in BLDC machines operating in a variety of operating conditions ranging from constant speed to continuous transient operation. This objective is addressed as three parts in this research. The first part experimentally …

The analysis and detection of faults in three phase induction machines using finite element techniques.
… machines with the fault condition of broken rotor bars. Where possible, results obtained from the finite element simulations arc compared directly with results obtained from a laboratory test rig machine having the same fault conditions. The purpose of the work was to enhance present …

The monitoring of induction motor starting transients with a view to early fault detection.
… 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 and the inter-relationships between parameters such as current, …

Condition Monitoring of VSD-fed Induction Motors
… [6]. These motors are of two types, the wound-rotor and the squirrel cage [1], [5], with the three-phase squirrel cage induction motor being the most common, constituting over 80% [7], [8]. On the other hand, variable frequency AC inverters are also of two types, the voltage source inverter …
