Purpose. The work is aimed to study the change in parameters of traction electric motors of trolleybuses during operation and improvement of the technical state control system, using modern diagnostic methods. Methodology. Solution of the scientific ... see more

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 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

The methods of determination of the optimal parametric series of boosters for the test desks for traction electric motors of direct current electric locomotives are offered in the article.

In the article a simulation model of traction direct drive on the basis of inductor motor with the axial magnetic flux realized in the visual programming environment Simulink is considered. At creation of the AI? model a method block diagrams is used.

In this article the research results of many authors on the effect of current interference from the existing electric rolling stock with induction traction motors (ITM) on the track circuits and the possibility of exceeding the train traffic safety standa... see more
