An approach for bearing fault detection in electrical motors

In this paper, a novel approach for fault detection and diagnosis of induction motors is proposed. This approach depends on determination of a common vector for each class, called the common vector approach (CVA). The common vector of each class represents invariant features or common properties of that class. Vibration signals measured from the rotor ball bearings of an induction motor are used in the experimental study. Experimental results indicate that the proposed approach can be efficiently used for the analysis of faulty conditions in induction motors. Copyright (C) 2007 John Wiley & Sons, Ltd.
