The results of a comparative analysis of formulas for calculating the mechanical characteristics of asynchronous traction motors are presented, as well as a new method of determining the absolute slip for the required moment is proposed.

The possibilities of asynchronous traction electric motor drive are considered at the certain coupling mass taking  into account the coupling restrictions. A variant of using the regulation law for electric motor drive allowing realizing traction for... see more

In the article the structural reliability of different variants of structured schemes of the steady-state converter for traction drive of promising multi-system electric locomotives with asynchronous traction engines is compared.

The mathematical modeling and circuit simulation of asynchronous propulsion drive unit with converters on IGBT transistors have been made. The possible noises appearing during drive’s operation have been determined. The spectral composition of phase curre... see more

The article is devoted to study of influence of the heating of asynchronous engine coils on the size of critical values of moment and absolute sliding.

The article provides the results of theoretical calculations of short circuit emergency operation modes in supply circuits of the stator windings of asynchronous tractive motors at start-up of the locomotive, hauling a freight train.

Our research offers a new perspective loading pattern of the 12-wheel double-feed freight electric locomotive with the asynchronous tractive motor using an adapter transformer with the high-frequency uncoupler. This will make it possible to decrease the t... see more

Made by the method of calculation of the absolute values of the authors of the slip, which provide the desired engine torque at various laws regulating the voltage. The analysis of the results. 

The computer modeling method and results of dynamical modes in asynchronous traction drive on perspective trunk diesel locomotives with voltage inverters by using DAT305 and DTA470 traction engines are present
