The problem raised by_x000D_
Mahon Electric Co Ltd. (in Thunder Bay, Ontario) is how to detect a broken rotor bar fault under low or no_x000D_
load conditions, which is also an ongoing problem in the industry, and a challenging task in this research field._x000D_
A lower load corresponds to a smaller slip, which makes it more difficult to detect rotor fault. To tackle this_x000D_
challenge, the objective of this project, in collaboration with Mahon Electric, is to develop a new slip spectral_x000D_
(SS) technique for broken rotor bar fault detection, under low or no loading. The proposed SS technique_x000D_
applies both electric current and vibration signals for fault detection. Specifically, 1) a smart sensor will be_x000D_
developed for more accurate rotor speed recognition and slip estimation; 2) Adaptive denoising filtering_x000D_
technique will be proposed to improve signal-to-noise ratio of the complex signal path from the faulty rotor bar_x000D_
to the current sensors; 3) A new approach will be suggested to demodulate average spectral characteristics over_x000D_
the bands with impulses for rotor bar fault detection under no load conditions. This project will be undertaken_x000D_
with close collaboration with Mahon Electric. The related research and testing will be performed in the_x000D_
company. The rich hands on experience the company's staff will be very helpful to make productive results of_x000D_
this project. The proposed SS technology can also be used for general online motor health condition_x000D_
monitoring to recognize the motor defect at its earliest stage so as to prevent machinery performance_x000D_
degradation, malfunction, or even devastating failures. The SS technology can benefit a wide array of Canadian_x000D_
companies to gain a competitive advantage in the related market by improving production quality and system_x000D_
reliability, and reducing costs., program purpose french : Electric motors are commonly used in various domestic and industrial applications. The problem raised by_x000D_
