Autor: Szolc Tomasz, Konowrocki Robert, Pochanke Andrzej

Publikováno v: MATEC Web of Conferences, Vol 285, p 00018 (2019)

In the paper there is presented a reliable structural model of the rotating mechanical systems as well as mathematical models of the stepping, synchronous and asynchronous motors, by means of which electromechanical coupling effects can be thoroughly

On the Range of Influence of Magnetic Core on Frequency Characteristics of Transformers

Autor: Tadeusz Daszczynski, Zbigniew Pochanke

Publikováno v: 2021 Progress in Applied Electrical Engineering (PAEE).

The main problem in interpreting the results of the sweep frequency response analysis (SFRA) diagnostic tests is the lack of measurement information on a specific type of transformer failure. Including therefore the so-called "Fingerprint" method, in

Dynamic aspects of design and maintenance of the rotating machinery applied in the mining industry

Autor: Szolc Tomasz, Konowrocki Robert, Pochanke Andrzej, MichajŁow Maciej

Publikováno v: E3S Web of Conferences, Vol 18, p 01010 (2017)

In the paper a dynamic behaviour of the selected typical group of rotating machines applied in the mining industry is investigated. These are the beater mills and crushers as well as blowers and compressors, all driven by the asynchronous motors. In
