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...

A test fixture and deembedding procedure for high-frequency substrate characterization

Creator:

Webb, Kyle M.

Abstract:

At frequencies exceeding 1-2 GHz, the substrate network models used in substrate coupling simulation must account for the reactive nature of the substrate. Unlike at low frequencies, where the purely resistive substrate models can be validated through DC resistance measurements, these high-frequency models, comprising reactive components, must be validated through...

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...
