Engines of the mine automated electric locomotive

Abstract

With the modern development of mining electrical engineering, a serial DC motor is used as a traction motor on mine electric locomotives. It best satisfies the requirements of mine electric locomotives when operating on mine haulage tracks. At present mine pumping tracks are characterized by very weak top structure, sharply variable gradients, the presence of curves of small radius of roundings and in some cases waterlogged and contaminated rails. Such condition of rolling tracks, naturally, leads to deterioration of rolling stock operation, rapid wear of running parts of electric locomotives and railcars - to increased resistance to movement of the entire train. Working conditions of the traction engine of mine electric locomotives usually have a sharply variable load value. Static resistance to motion often takes negative values. In the presence of other additional resistance to motion, the traction motor actually operates all the time in transient modes - in acceleration and deceleration.
