The principle of the operation of the presented magnetic refrigerator is based on the rotary movement of active magnetic regenerators (AMRs) with magnetocaloric materials and on the stationary magnetic field generated by permanent magnets NdFeB. After a short description of the basics of magnetic refrigeration, this paper presents the development and analysis of the structure for generating the magnetic field and the basic operational principle of the first prototype magnetic refrigerator, which was developed at the Faculty of Mechanical Engineering. The second part of the paper provides a description of the development process for certain key elements of the complete magnetic refrigeration systemPrispevek opisuje razvoj in zasnovo prototipnega rotirajočega magnetnega hladilnika. Osnovni princip delovanja predstavljenega magnetnega hladilnika temelji na vrtilnem gibanju aktivnih magnetnih regeneratorjev (AMR) z magneto-kaloričnim materialom ter na statičnem magnetnem polju, ki ga ustvarjajo permanentni magneti NdFeB. Po kratkem opisu osnov tehnologije magnetnega hlajenja je v prispevku predstavljen razvoj in analiza strukture za ustvarjanje magnetnega polja in osnovni princip delovanja prvega prototipnega magnetnega hladilnika razvitega na Fakulteti za strojništvo. V drugem delu prispevka pa je opisan razvoj in zasnova ter oblikovanje določenih ključnih elementov celotnega sistema magnetnega hladilnikaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
