A thorough thermal study on a fleet of direct current (dc) traction motors which were found to suffer from overheating after three years of full operations is described. A finite difference model is developed to simulate the temperature profile at different parts inside the traction motor. An empty vehicle loaded with drums of water was also used to simulate the full payload of the light rail vehicle experimentally. The simulation results agreed well with the experimental data, and it is likely that the armature of the traction motor will run cooler if the field shunt is disconnected at low speeds.
