A traction motor fault diagnosis method and apparatus, which are applied to a traction motor fault diagnosis system. In the method, a train traction motor is taken as an object, and on the premise of not adding a new sensor and not carrying out additional device transformations on a train traction system, fault diagnosis for a traction motor bearing and fault diagnosis for stator coil insulation are realized by using a bearing fault diagnosis parameter and a stator coil insulation fault diagnosis parameter of the traction motor and by respectively calling a preset gradient boosted tree model and a preset fuzzy clustering model, thus reducing traction motor fault diagnosis costs.
