In the development process of HXD3 electric locomotive, mature and reliable new technology at home and abroad is adopted. The locomotive adopts 6-axis freight for the purpose of large-scale freight traction on Chinas domestic main line. The high-power AC drive electric locomotive design platform adopts new technologies such as PWM vector control, closed traction transformer and integral drive device to minimize environmental protection and reduce maintenance workload. In addition, considering that it can operate in China, the locomotive meets the conditions of an ambient temperature of -40℃～40℃and an altitude of 2,500 m or less. The locomotive can be controlled by three groups of locomotives. The locomotive can meet the needs of Chinas railway heavy-duty and fast cargo transportation. This paper is mainly to understand the structural characteristics of HXD3 electric locomotive traction motor. Through the detailed description of the main technical parameters and characteristics of HXD3 electric locomotive traction motor, the structure of HXD3 traction motor and the characteristics, maintenance and overhaul of traction motor, It is clear that we know the structural characteristics of the HXD3 traction motor and h
