In the article, the authors describe, using the example of a selected class of technical means, their concept of replacing the “classical” linear management (exploitation) model with a circular economy (CE) model. An example of an object for which the authors plan to test the feasibility of the concept presented above is a household washing machine driven by a DC motor. The description of this object included in the article considers its complexity and multiplicity of assemblies, sub-assemblies, and elements. The DC electric motor driving the washing machine was considered the most important from the point of view of the created model, especially in terms of the possibility of maintenance and repair. For such an engine, the article presents the maintenance and disposal model as elements of the concept of building a ‘circular’ business model. The authors assumed that the formal basis for such a model would be the so-called circular model. The methodology and plan of the research carried out at Super Asia washing machine company in Pakistan were introduced, and the research results were shown. With the use of these results, an attempt was made to assess the requirements that the application of the CE business model places on manufacturers of a selected class of devices, both in their manufacture, repair, sharing and dematerialization. The concept of further research is described at the end of the article.

This paper synthesizes the models of the current to be applied to the armature of a drive direct-current series electric motor used within an electric drive system of an electrically propelled truck, such models being optimal in terms of battery power expenditure minimization. The paper offers a parameter identification method for the synthesized models to be used either for a loaded truck or for an empty one, either for a horizontal run or for a downhill/uphill run.

W artykule przedstawiony został sposób modelowania prądu płynącego przez obwód silnika, stosowany w układzie napędowym wózka pojazdu ciężarowego. Przedstawiony został dobór modelu optymalnego z punktu widzenia minimalizacji wymaganego nakładu energii akumulatora. W artykule zawarto również metodę identyfikacji parametrów dla przedstawionych modeli, w tym przeznaczone zarówno dla pustego jak i obciążonego wózka pojazdu, jadącego po powierzchni płaskiej i pochylonej.

W artykule przedstawiono wyniki badań laboratoryjnego układu małej mocy "ogniwo paliwowe - silnik elektryczny". Opisano specyfikę pracy alkalicznego ogniwa paliwowego i aspekty jego zastosowania w elektrycznym układzie napędowym. Zaprezentowano wpływ czynników eksploatacyjnych ogniwa na charakterystykę prędkościowo-obciążeniową zasilanego silnika. Analizie poddano dwa różne typy silników prądu stałego.
