Abstract
Jedna od faza kod projektiranja sinkronih motora s trajnim magnetima elektromagnetski je proračun za koji je potrebno poznavanje magnetskih i termičkih svojstva materijala od kojih će elektromotor biti izrađen. Veliku ulogu u odabiru materijala ima i namjena za koju se projektira motor. Kroz poglavlja prikazana su svojstva i smjernice za odabir trajnih magneta, električnih limova i namota motora. Kod odabira trajnih magneta posebna pozornost posvećena je krivulji demagnetizacije magneta, a kod električnih limova modelima za proračun gubitaka u željezu. Objašnjene su i nomenklature pojedinih materijala za što lakše snalaženje u bazi podataka koja je napravljena u Matlab GUI sučelju. Baza materijala omogućuje pregledavanje svojstva komercijalno dostupnih trajnih magneta i magnetski neorijentiranih električnih limova te unošenje novih materijala. Kod trajnih magneta magnetska svojstva magneta proračunavaju se na unesenu temperaturu te postoji mogućnost otvaranja kataloga proizvođača u kojem je vidljiva krivulja demagnetizacije magneta. Korisno svojstvo aplikacije je proračun gubitaka u željezu za odabrani električni lim prema ponuđenim modelima. Za bakrene ili aluminijske namote aplikacija daje mogućnost proračuna njihove vodljivosti i otpornosti na unesenu temperaturu.
Abstract (english)
Electromagnetic design is an essential phase in the development of the synchronous permanent magnet motor drives. It is necessary to know the magnetic and thermal properties of the materials that will be used for this purpose. In the selection of the materials the future work conditions and desired performance of the motor are also important. Properties and advices useful for selection of permanent magnets, electrical steels, winding materials are presented through several chapters of this Master work. In the chapter about permanent magnets special attention is devoted to demagnetising curve of a permanent magnet and in the chapter about electrical steel to the core loss estimation models. To provide the user an easier navigation in the database of the materials with the GUI interface nomenclature of the earlier mentioned materials is also explained. The database of the materials allows the user browsing trough the properties of the commercially available permanent magnets and non grain oriented electrical steels and also expanding the database by adding new materials. Extra feature added in the permanent magnet browser allows the user calculation of the magnetic properties at desired temperature. In electrical steel menu the user can select one of the models for the core loss estimation. The winding menu is used for calculation of resistivity and conductivity of winding material, copper or aluminium, at desired temperature.
