牵引电机进行反馈试验,不仅制造部门在成品例行试验中要进行,就是一些修理单位,如众多具备架修能力的电力或内燃机务段,也需通过反馈试验来考核牵引电机的修理质量。反馈试验最常采用的是带有升压机的反馈试验线路,如图1所示。同型号的两台牵引电机进行反馈试验时,由于磁路以及定装中引起的特性差异,常常为正常进行反馈试验带来一些
Traction motor feedback test, not only the manufacturing sector in the finished product routine test to be carried out, that is, some repair units, such as a large number of repair or repair with the power of the engine section, but also through the feedback test to assess the quality of traction motor repair. The most commonly used feedback test is a feedback test circuit with a booster, as shown in Figure 1. The same type of two traction motors for feedback test, due to the magnetic circuit and the assembly caused by the characteristics of differences, often for normal feedback test to bring some
