    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.

    VPLYV LETECKEJ DOPRAVY NA ŽIVOTNÉ PROSTREDIE
    (Žilinská univerzita v Žiline, 2020) Turkinevych, Yelyzaveta; Jarošová, Miriam
    The relevance of the topic is due to the fact that in the transport sector, the aviation industry is one of the sources of global warming and climate change. The average number of flights worldwide is up to 102,465 per day, and this number is constantly growing, which has a major impact on the climate. Climate change is currently a huge problem, global warming is evident and unquestionable. It follows that our effort to conquer nature is a great threat to all of humanity. The aim of this work was to analyze the impact of air transport on the environment from several perspectives. The work is divided into three parts. The first chapter describes the historical development of the issue in the world. The second chapter deals with the analysis of global warming and destabilizing environmental factors. There are descrribed different types of ecological pollution. The last third part discusses ways to minimize the impact of aviation on the environment.
