In order to design a simple and robust generator, models were constructed out of permanent magnets, steel and windings. In all five generator models, round movers were used in spherical and cylindrical form- for four models solely permanent magnets were used, and in one model, there was steel present in the mover. The movers are slid or rolled through a tube, and induce voltage in the stator winding. All windings were constructed with the same cross- -section dimensions and number of turns. To compare different models, 3D analysis with the Finite Element Method was performed, in order to determine the magnetic flux through the windings. The induced voltage was calculated using the results of the analysis. As a result of the different winding geometries, the average turn length varied for the different designs, subsequently altering resistance and inductance, which affected the generator`s power output and losses. To simulate the generator`s dynamics, an equivalent circuit model was constructed using the Simulink software and data obtained previously from a 3D electromagnetic analysis. With the Simulink model, we coupled the mechanical and electrical systems together to acquire the harvester yields"},{"@xml:lang":"sl","#text":"V članku je predstavljenih 5 različnih izvedb cevnega nizkofrekvenčnega elektromehanskega generatorja za izrabo energije gibanja. Z namenom oblikovanja preprostega in robustnega generatorja so modeli sestavljeni iz trajnih magnetov, jekla in navitij. Pri vseh modelih generatorjev sta za okrogli gibljivi del uporabljeni sferična in cilindrična oblika - pri štirih modelih so uporabljeni izključno trajni magneti, pri enem pa je prisotno jeklo. Gibljivi del drsi ali pa se valja skozi cev in pri tem inducira napetost v navitju statorja. Pri vsakem modelu imajo navitja enak presek ter enako število ovojev. Za primerjavo različnih modelov je bila izvedena 3D-analiza z uporabo metode končnih elementov za določitev magnetnega pretoka skozi navitja, na podlagi katerih je izračunana inducirana napetost. Zaradi različnih geometrij navitij se je povprečna dolžina ovoja pri različnih izvedbah spreminjala, kar je posledično spreminjalo upornost in induktivnost ter s tem vplivalo na izhodno moč in izgube generatorja. Za simulacijo dinamike generatorjev je bilo z uporabo programa Simulink in predhodno pridobljenih podatkov iz 3D-elektromagnetne analize določeno nadomestno vezje modela. Za določanje izplena smo z modelom v programu Simulink združili mehanske in električne sisteme"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-A1MHJXRU","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-A1MHJXRU"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-A1MHJXRU/c67cce2f-b59e-49c7-a036-040cfb8c7033/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Mariboru, Fakulteta za energetiko"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-A1MHJXRU/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-A1MHJXRU"}}}}
