The article deals with the analysis of the work of Traction Motor Protecting System on electric locomotives DE1, which protects the motors from inner and outer short circuits in the mode of recuperative breaking. The calculations have revealed that the sy... see more

A comparative characteristic of different concepts and expressions for determination of reactive power in the circuits with non-sinusoidal electric values has been given. For the first Ukrainian electric locomotives of DE1 type with the system of DC elect... see more

The article provides brief description of a technical project for reequipping the electric locomotives VL80? and VL80S with smooth thyristor adjusters of tractive motors with the single automatic control system.

The article examines transitional processes in the power circuit of tractive motors and their influence on the work of grading automatic starting of EMU trains ER2R, ER2? and EPL2?. Recommendations have been developed for increasing reliability of operati... see more

Theoretical research of voltage emissions has been conducted for the collector of electric locomotive DE1. The comparative results of theoretical and experimental calculations have been provided.

The subject matter of the research in the article is the process of restoring the quality and accuracy of the working surface of the wheelsets of the main electric locomotives, electric sections. The purpose of the work is to develop a modeling method for... see more

Assessment of the value of thermal residual stresses in stiffness ribs produced in accordance with the second constructive and set on in bogie frames of ??60 electric locomotives. Resonant frequency of their lateral oscillation is calculated. A conclusion... see more

The authors suggest a system of automatic control of braking force at recuperation ofd.c.electric  locomotives, in which the necessary braking effort is generated by the decisive unit, constructed on the basis of a microcontroller, according to the p... see more

The article represents some results of computer modelling of dynamic processes in the tractive drive of freight and passenger electric locomotives in realization of marginal friction forces and their interaction with anti-boxing system of boxing preventio... see more
