Motorové jednotky nezávislej trakcie s jednonápravovým podvozkom
(University of Žilina, 2024) Bučko, Martin; Dižo, Ján; Blatnický, Miroslav; Lovska, Alyona
The article analyses the current state of the motor wagons and units with implemented single-axle bogies, operated on local lines as well as abroad. The technical parameters of individual rolling stock were compared. The main goal of the article is to present an overview of independent traction multiple units, which are equipped with a single-axle bogie. There are described rail vehicles used on only in the Slovak Republic, but also in Europe. As the use of this type of rail vehicle is on the decline, this overview reflects the current state in this field of rail vehicle design, at which, information is complemented with corresponding illustrations.
Porovnanie systémov prenosu výkonu koľajových vozidiel s nezávislou trakciou
(University of Žilina, 2025) Bučko, Martin; Samaš, Vladimír; Dižo, Ján; Blatnický, Miroslav
The article deals with independent traction rail vehicles, mainly the power transmission type. The advantages and disadvantages of different types of power transmission for independent traction vehicles are compared, including the use of a particular type in each category of rail vehicles and a schematic illustration.
Systèmes de traction électrique modernes: avantages des moteurs PMSM dans le transport ferroviaire
(University of Žilina, 2025) Samaš, Vladimír; Bučko, Martin; Gerlici, Juraj; Dižo, Ján; Blatnický, Miroslav
Currently, there is a growing global emphasis on environmentally friendly transportation, with railway transport being one of the most efficient and sustainable modes of travel. This form of transport is distinguished by low rolling resistance, which leads to reduced energy consumption for both passenger and freight transport. Electric traction, widely used in railway vehicles, can be categorized as either dependent or independent. Dependent electric traction represents an environmentally friendly solution, as it eliminates the need for petroleum based fuels and instead utilizes electricity drawn from the grid. However, this approach is truly ecological only when the electricity is generated from renewable and sustainable sources. Modern electric traction systems rely on electric motors, and this article aims to provide a detailed analysis of the application of permanent magnet synchronous motors (PMSM) in railway transport, particularly in the context of electric traction. PMSM motors are characterized by high efficiency and excellent controllability, making them well-suited for extensive use in railway applications. Their significant potential in this field positions them as a promising solution for future sustainable and efficient transport systems.
