Brief Introduction

 

The reason why there is such a doubt is because in the rail transit industry, where the technical solutions are relatively conservative, DC-driven locomotives and shunt and compound motors have not changed much in the development process of 20 or 30 years or more.

 

Of course, this also has a lot to do with the vehicle system. It's over, the subtext is that it's time to change the course. Taking DF4D, a common domestic internal combustion DC-driven locomotive, as an example, the weight of a single traction motor is about 3000kg, the rated power of the motor is about 530kW, and the power density is about 0.18kW/kg.

 

Compared with the HXD1 series electric AC transmission locomotive developed on the introduction of German Siemens technology, the weight of a single motor is about 2500kg, the rated power is about 1200kW, and the power density is about 0.48kW/kg, which is almost three times that of DF4D. Looking at it this way, it seems that the development of shunt and compound motors has come to an end. I asked deeoseek this question.

 

Rail transit is a relatively closed circle after all. compound DC motor are actually developing rapidly in other industries.
