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 efficiencyStrukturne 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 povečataTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
