摘　　要：本文主要探讨了交—直—交传动机车轮径偏差、异步牵引电动机转矩和电流偏差、轮周牵引力偏差以及电动机转差率之间的数量关系。给出的计算公式不要求知道牵引电动机的具体特性参数和供电电压及频率,适用于牵引电动机尚未设计出来前,对交—直—交传动机车的总体方案进行分析研究。文中还对上述偏差及牵引电动机转差率的数值提出了建议。The article has discussed the relations between wheel diameter deviation, torque and curretn deviation of asynchronous traction motor, deviation of the tractive effort at wheel rim and motor slip. The formula given does not require detailed parameters of traction motor, feeding voltage and frequency, suitable for analysis or research on the general scheme of AC-DC-AC electric drive locomotive before the traction motor is designed. The author also put forward some suggestions on data of the deviations and motor slip mentioned above.
