Due to the high speeds of the rotor during operation its mass centricity is very important for the service life of the bearings, low noise and smooth running. This paper presents the production of claw poles using cold-forming technology, and a focus on reducing the electricity. Achieving this aim will mean a step towards shortening the time needed for automated balancing. We start with the problem of production and principle of balancing, this is followed by an experimental analysis of current production and a FEM analysis, which helps to describe the reasons why unbalance occurs. Emphasis is placed on work towards improving the tooling system for achieving well-balanced claw poles after cold forming"},{"@xml:lang":"sl","#text":"Krempljasti poli so še vedno največji in najtežji sestavni del rotorja alternatorjev, ki bo vsaj še nekaj časa ustvarjal električno energijo v motornih vozilih. Zaradi visokih vrtljajev, ki jih alternator med delovanjem doseže, je masna uravnoteženost rotorja bistvenega pomena za dobo trajanja ležajev, majhen hrup in miren tek. Prispevek obravnava izdelavo krempljastih polov s hladnim preoblikovanjem, pri čemer je poudarek na zmanjšanju njihove neuravnoteženosti, s čemer bi bistveno pripomogli k pospešitvi avtomatskega uravnoteženja rotorjev. V začetku je na kratko orisan problem ter samo načelo uravnoteženja. V nadaljevanju sledi eksperimentalna analiza sedanje proizvodnje, z uporabo metode končnih elementov pa razložimo vzroke za pojav neuravnoteženosti. Poudarek je dan raziskavam v smeri izboljšav sedanjega orodnega sistema za doseganje majhne neuravnoteženosti krempljastih polov"}],"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-DFCH0RP4","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-DFCH0RP4"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-DFCH0RP4/7db96cc4-e503-42ca-86d5-cd0a7e748a3b/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 Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-DFCH0RP4/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-DFCH0RP4"}}}}
