The bearing fault has a significant percentage to the electric machines, why a study in this setting is needed. The modified winding function approach theory (MWFA) is often used to model this fault. The influence of load and slip were studied even checking the corresponding measures proposed by the literature formulas of the characteristic frequencies. Both types of bearing defects must be processed...
This paper presents a method of detecting rotor faults in induction motors using the fast orthogonal search (FOS). Proper online condition monitoring of induction machines is very important to ensure safe operation, timely maintenance, and efficiency. It has been shown that when a fault occurs in the rotor, it will exhibit itself as a series of sidebands around the fundamental frequency in the stator...
