[en] In recent years, improving energy efficiency has become a primary concern in not only providing ecological benefits but also lowering operational costs. These benefits would then enable the creation of more attractive products. Thus, simplifying the design process and reducing manufacturing costs are the objectives of manufacturers worldwide. The realm of electric machines has followed the same trend. The main objective of this thesis is to define a methodology for the design of axial machines. This methodology is divided into the following steps. First, the features and limitations of the application are defined, so the characteristics of the machine to be designed can be specified. Once these specifications are established, the design process can be performed. The design is carried out by first using analytical tools and is then further refined using numerical tools. This design specifies the characteristics of the future machine. The development of these tools forms the core of this thesis. Sizing equations based on the laws of electromagnetism were developed as analytical tools. An advanced model based on the Fourier series was then constructed. The finite element method (FEM) focused on axial machines is used for the numerical tools. The two environments offered by FEM platforms are examined: two dimensional environments and three dimensional environments. In order to validate the proposed methodology, a prototype oriented to an elevation application is built. This machine is created following the methodology presented in the thesis. Furthermore, some small prototypes are fabricated to validate the tools in addition to the methodology, which lends added value to the research work.

[eu] Azken urte hauetan efizientzia energetikoak hartu du protagonismo nagusia. Efizientzia hobetzeak ekologikoki onurak eskaintzeaz gain funtzionamendu kosteak murriztea ere ekartzen du, produktu erakargarriagoak sortzea bideratuz. Honez gain diseinu prozesua arintzea eta fabrikazio kosteak murriztea ere fabrikatzaile ororen jomuga izan dira. Makina elektrikoen munduak bide bera jarraitu du. Hortaz tesi honen helburu nagusia fluxu axialeko makinak diseinatzeko metodologia oso bat proposatzea izan da. Metodologia hau ondorengo etapa desberdinetan banatzen da. Hasteko aplikazioaren betebehar zein mugak definitzen dira horrela makinaren ezaugarriak zehazteko. Behin ezaugarri hauek izanda makinaren diseinua burutzen da. Diseinu hau lehenik erreminta analitikoen bidez egiten da ondoren numerikoen laguntzaz diseinua fintzeko. Diseinu honetatik eraikiko den makina zehazten da. Aipatu erreminta hauen definizioa izan da tesiaren muin nagusia. Erreminta analitikoei dagokienez, lehenik lege elektromagnetikoetan oinarritutako oinarrizko dimentsionatze ekuazioak definitu dira. Bestetik Fourier-en serietan oinarrituriko modelo garatua ere planteatu da. Ondoren erreminta numerikoen inguruan elementu finituen metodoa (FEM) aurkeztu da makina axialen diseinura nola bideratu azalduz. FEM plataformek eskaintzen dituzten bi dimentsiotako zein hiru dimentsiotako inguruneak landu direlarik. Prozesu honen baliagarritasuna frogatzeko igogailu aplikazio batera bideratutako prototipo esperimental bat ere eraiki da. Prototipo hau eraikitzeko, tesian proposatutako metodologia jarraitu da pausuz pausu. Gainera beste prototipo txikiago batzuk ere eraiki dira metodologia bera frogatzeko baino, erremintak balioztatzeko asmoz. Honek gainera ikerketari balio erantsi bat eman ahal izan diolarik.
