20.500.12556/DiRROS-20867 Magnetic properties of as-cast iron-cobalt alloys Magnetne lastnosti litih železo-kobaltovih zlitin The structural and magnetic properties of iron-cobalt alloys (FeCoV) were compared to those of electrical steel alloys. The latter are widely used for the ferromagnetic cores of electric motors. However, the as-cast and rolled FeCoV alloys, which were ana lysed, showed enhanced magnetic properties compared to electrical steel alloys. Moreover, since they can be cast directly into the final shape of the rotor’s main structure (excluding the pole shoes, which must be laminated) for a wound-rotor synchronous electric motor, the production becomes more cost-effective and energy-efficient. In addition, the performance of the electric motor is improved in terms of mechanical output power and energy efficiency Strukturne in magnetne lastnosti železo-kobaltove zlitine (FeCoV) smo primerjali z zlitino elektro pločevine. Slednja se pogosto uporablja za feromagnetna jedra v elektromotorjih. Vendar pa so ulite in valjane zlitine FeCoV, ki smo jih analizirali, pokazale izboljšane magnetne lastnosti v primerjavi z zlitinami elektro pločevine. Poleg tega jih je mogoče ulivati neposredno v končno obliko in s tem formirati glavni del rotorja (razen polovih čevljev, ki morajo biti laminirani) sinhronskega elektromotorja z mnavitim rotorjem, zato je proizvodnja cenejša, porabljena energija pa manjša. Mehanska močna gredi elektromotorja ter energijski izkoristek motorja se prav tako povečata. iron-cobalt alloys ferromagnetic materials electromagnetic energy conversion železo-kobaltove zlitine feromagnetni materiali elektromagnetna pretvorba energije true false true Inštitut za kovinske materiale in tehnologije Slovenija Angleški jezik Slovenski jezik © Inštitut za kovinske materiale in tehnologije Neznano 2024-11-25 13:10:15 2024-11-25 13:10:16 2024-11-26 03:36:15 0000-00-00 00:00:00 2024 0 0 str. 657-662 št. 5 Let. 58 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-10-17 621.313/.314 1580-2949 10.17222/mit.2024.1228 213035779 RAZ_Vukotic_Mario_2024.pdf RAZ_Vukotic_Mario_2024.pdf 1 AB7396987EDD421C266C801539F0C357 75cc49dc6968970684a8bc2c8ce81e38d7cc9a542d7b3262fcc45f885455ceec 6680c598-ab27-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29489 https://mater-tehnol.si/index.php/MatTech/article/view/1228 1 417b024d-ab26-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29488 Inštitut za kovinske materiale in tehnologije 0 0 0
