Electrical and air equipment of 2ES5K AC electric locomotive
Е5К (E5K) and 2/3/4ЕС5К (ES5K) “Ермак “ (The Ermak – the series is named in honour of Russia's national hero Ermak, conqueror of Siberia in the times of Ivan the Terrible) – a family of new 25 kV AC mainline freight electric locomotives with four-axle sections equipped with collector traction motors. The number of sections can be from one to four (internal - booster without cab). These electric locomotives are the next evolutionary stage in the development of ВЛ80 (VL80) freight electric locomotives and are positioned as their main replacement. Like the VL80, they were developed by the All-Russian Research Institute of Electric Locomotive Building (VELNII) in Novocherkassk and have been produced since 2004 at the Novocherkassk Electric Locomotive Plant, a part of the CJSC Transmashholding concern, currently being the most mass-produced family of Russian electric locomotives. More than 2200 electric locomotives have already been built, including 1500 three-section 3ES5K. In most mechanical parts they are unified with the 2/3ЭС4К (ES4K) family of 2–3 section DC electric locomotives, which are the successors of another mass-produced locomotive VL10 built in Georgia and in Russia at NEVZ. www.flickr.com/photos/cetus13/53285531192/in/dateposted/
The locomotive has a steel wagon-type body with a main frame, on which a plastic block control cabin and a set of equipment are mounted. The running gear is designed with axle-axle suspension of traction electric motors with motor-axle plain bearings. The bogies of the low-production 6-axle freight-passenger (Bo'Bo'Bo') electric locomotive ВЛ65 (VL65) are used, this bogie differs from the bogies of VL80 and VL85 by the absence of leaf springs (flexicoil suspension is used), and from the bogie of ВЛ80, in addition, by the absence of kingpins, the force transmission is through the central inclined link. The locomotive is equipped with advanced 850 kW collector traction motors НБ-514Д (NB-514D; in new modification ES5S is used asynchronous motors ДТА-1100 and IGBT transistors), as well as a microprocessor control system that provides manual and automatic motion control, diagnostics of motion parameters and operation of all locomotive equipment, electric regenerative braking. Its DC counterpart uses different 800 kW DTC-800 traction motors and has a dynamic brake in addition to regenerative braking (that can be seen in roof comparison)
