电力牵引较之内燃牵引有显著的优越性,因此,有必要从内燃牵引过渡到电力牵引。在改造机车的过程中,最好保留机车的牵引电动机和某些机械部件(如转向架)不变。牵引电动机是机车最重要的部件之一。考虑到在一年内生产的牵引电动机的总功率约为2000000瓩,因此就很有必要制造工作范围尽可能广,工作可靠而利用率又高的牵引电动机。在我们看来,这是决定整个铁路电气化成效的最重要的
Electric traction has a significant advantage over internal combustion traction, so it is necessary to transition from internal combustion to electric traction. In the process of rebuilding a locomotive, it is better to keep the locomotive’s traction motor and certain mechanical components (such as bogies) unchanged. Traction motor is one of the most important parts of the locomotive. Considering that the total power of a traction motor produced in a year is about 2000000 瓩, it is necessary to manufacture a traction motor that has as wide a range of work as possible, a reliable operation and a high utilization rate. In our opinion, this is the most important factor that determines the electrification effect of the entire railway
