Induction motors are widely used in traction drives of rolling stock of railways. For timely detection of faults that may occur in an induction motor during operation, a functional diagnostics system is used. Thanks to such a system, it is possible to detect and prevent further development of a fault at the initial stage of its occurrence in real time. When developing a functional diagnostics system, it is important to select the most relevant method for processing diagnostic information for a specific type of damage. One of the most difficult to detect defects is rotor eccentricity. Rotor eccentricity is a consequence of a wide range of motor damages that must be monitored during operation. The paper offers an analysis of modern methods for processing diagnostic information that can be used to build a functional diagnostics system for the presence of rotor eccentricity in an induction traction motor and also provides recommendations for choosing a more effective method.
