Traction drives with vector control are widely used on mainline locomotives with induction motors. Traction motors can fail due to malfunctions that occur during the operation of locomotives. Real-time functional diagnostic systems are necessary to prevent the failure of traction motors. The implementation of such systems will allow to detect the occurrence of malfunctions in the traction motor at the initial stage and prevent the further development of the defect. In the work, a structural diagram of functional diagnostics for monitoring the condition of the rotor of an induction motor is proposed and an algorithm for its operation is developed.
