Abstract

The invention provides a traction motor fault diagnosis method and device. The method is applied to a traction motor fault diagnosis system. In the method, a train traction motor is used as an object,on the premise of not additionally arranging a sensor and not additionally carrying out equipment transformation on a train traction system, and by utilizing the bearing fault diagnosis parameter andthe stator coil insulation fault diagnosis parameter of the traction motor, a preset gradient boosting tree model and a preset fuzzy clustering model are respectively called to realize fault diagnosis of a traction motor bearing and fault diagnosis of stator coil insulation, thereby reducing the fault diagnosis cost of the traction motor.

Description

technical field [0001] The present application relates to the technical field of motor fault diagnosis, in particular to a traction motor fault diagnosis method and device. Background technique [0002] With the wide application of rail trains, in electric railway rolling stock, the traction motor is the core component to realize the conversion of electrical energy and mechanical energy, and undertakes the important task of power output in the operation of rolling stock, which has great influence on the operating efficiency and safety of railway rolling stock. important influence. Operation practice shows that the operating conditions of rail train traction motors are complex and changeable. impact, it is easy to cause the traction motor to fail. Once the traction motor breaks down, it will affect the driving order and cause heavy economic losses, or lead to safety accidents and endanger personal safety. [0003] According to the survey results, 40% of traction motor fail...
