Influence of adjustable speed drive on induction motor fault detection using stator current monitoring.

Creator:

Al-Shahrani, Ali

Abstract:

The detection of motor faults at their incipient stage is of prime importance to any industrial plant. The introduction of adjustable speed drives has improved the control and the efficiency of induction motors, however, this has changed the nature of motor faults and how they can be detected. Current signature...

Detection of incipient rotor bar faults and air-gap asymmetries in squirrel-cage motors using stator current monitoring

Creator:

Al Tuaimi, Hamad A.

Abstract:

Preventative motor fault detection is of prime importance for modern plant management. During research into rotor faults, performed at the Motor Systems Resource Facility (MSRF), an optimized rotor fault detection and classification method was proposed. In critical process applications, the suggested method would provide the foundation for continually monitoring a...

Detection of induction motor stator abnormalities using motor current signature analysis

Creator:

Bin Eid, Ghassan A.

Abstract:

Induction motors are considered to be the work horse in all types of today's industries. In all mechanical applications, using an induction motor is considered to be the preferable, if not the optimum selection. Their failures, on the other hand, cause an interruption equal to their volume of dependency in...
