The computer aided design process was based on calculations employing 2D and 3D finite element method. Finite element method is able to perform magnetic field calculations based on machine geometry dimensions considering the nonlinearities of the magnetic materials. In contrast to other work from literature, this work deals with radial-radial electric machine concept with one burried permanent magnet (PM) per pole on the outer rotor. Consequently, the target one PM per pole design demands specific magnetic flux barriers implemented in the outer rotor in order that minimum flux leakage is assured. Using one PM per pole can be more cost effective compared to machines from literature which utilize two PMs per pole. Moreover, in contrast to the surface mounted PMs, the problems associated with centrifugal forces at higher rotor speeds can be avoided by burying the PMs. Because of the newly proposed outer rotor design, special attention has been given to investigation of the most appropriate stator-slot/outer-rotor pole/inner-rotor slot number combination. The DRPMSM performance with six different slot-pole-slot combinations was evaluated based on post-processing of results from finite element analyses (FEA). Considering the fixed structure features and the given criteria, the best possible combination in the analysis presents the basis for the DRPMSM prototype construction. The FEA based DRPMSM design was manufactured as a prototype, which has been experimentally validated and its performance has been thoroughly evaluated under different operating conditions. The agreement between numerically calculated and measured results is good. Furthermore, an experimental method to determine the magnetic coupling between the active parts of the manufactured DRPMSM is proposed</dc:description><dc:description xml:lang="sl">Doktorska disertacija obravnava postopek načrtovanja, analizo in izdelavo prototipa posebnega sinhronskega stroja s trajnimi magneti in dvojnim rotorjem (SSTMDR) ter utemeljitev vzročno-posledičnih povezav med magnetno sklopljenimi aktivnimi deli SSTMDR, namenjenega za uporabo v naprednih hibridnih pogonih vozil. Predviden postopek načrtovanja sloni na 2D in 3D izračunih modela SSTMDR s pomočjo metode končnih elementov (MKE), kjer je upoštevan vpliv geometrije stroja, vpliv magnetnih nelinearnosti stroja in materiala trajnih magnetov v ustaljenih obratovalnih stanjih. Poseben poudarekv fazi načrtovanja stroja je namenjen razvoju nove konstrukcije zunanjega rotorja SSTMDR, ki sloni na izvedbi zunanjega rotorja s potopljenimi trajnimi magneti (TM) in enim TM na pol ter izgradnji dodatnih magnetnih pregrad, ki pomembno vplivajo na karakteristike stroja. Predlagana izvedba z uporabo potopljenih TM in uporabi enega TM na pol tako bistveno zmanjšuje celoten volumen TM v SSTMDR, prav tako pa odpravlja težave povezane s centrifugalno silo, ki lahko nastopijo pri višjih vrtljajih z uporabo površinskih TM. V nadaljevanju je kot ena izmed ključnih faz konstruiranja SSTMDR predstavljena analiza vpliva števila statorskih utorov/polov zunanjega rotorja/utorov notranjega rotorja na karakteristike stroja. Na podlagi podanih kriterijev predstavlja najugodnejša kombinacija v opravljeni analizi osnovo za izgradnjo prototipa SSTMDR. Izdelan prototip SSTMDR tako omogoča verifikacijo ustreznosti predlaganega postopka načrtovanja stroja in verifikacijo principa delovanja SSTMDR. Eksperimentalno določanje elektromehanskih karakteristik stroja je izvedeno za primer generatorskih testov SSTMDR s pasivnim bremenom brez uporabe vodenja, kakor tudi za primer motorskega in kombiniranega motorskogeneratorskega režima delovanja, kjer je za delovanje potrebno ustrezno vodenje stroja. Ujemanje izračunanih in izmerjenih vrednosti je dobro. S predlaganim eksperimentalnim pristopom so ob koncu naloge določene še magnetno nelinearne karakteristike magnetnih sklepov, s pomočjo katerih smo opazovali vplive magnetne sklopljenosti stroja</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">visokošolska dela</dc:type><dc:type xml:lang="en">theses and dissertations</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q1266946" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-8XBNPUKJ"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-8XBNPUKJ" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-8XBNPUKJ/8e-6a42c92ac61c840d3-a-9-e37874d815c/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Mariboru, Fakulteta za elektrotehniko računalništvo in informatiko</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-8XBNPUKJ/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-8XBNPUKJ" /></ore:Aggregation></rdf:RDF>
