20.500.12556/RUL-173312 Designing an automated dismantling line for permanent magnet synchronous motors Načrtovanje avtomatizirane linije za razstavljanje sinhronskih motorjev s trajnimi magneti In this master's thesis, the process of designing an automated line for dismantling motors with permanent magnets from electric vehicles is presented. The focus was on developing a methodology for effective motor dismantling and magnet extraction from the rotor. In the first part of the thesis, the need for motor recycling is defined through the need to recover rare earth elements as critical materials. In this part, the concepts of circular economy and urban mining are introduced as the main concepts for the sustainable use of these elements in the European Union. In the second part of the thesis, manual disassembly of the motor from the Nissan Leaf electric vehicle was carried out, and the potential of recovery of rare earth elements from the rotor of that motor was analyzed through the obtained magnets. The dismantling process was approached systematically in order to define each necessary step, its complexity, and execution time. It was concluded that the demagnetization step of the rotor is necessary and that this step is the most demanding in terms of time and invested electrical energy. This analysis served as the basis for the design of the automated line. In the third part of the thesis, the requirements for an automated line are presented, derived from the knowledge gained during manual dismantling. The concept of the automated line was defined, and a digital model was created in the Siemens Plant Simulation software. On the digital model, two simulations were performed to validate the selection of the demagnetization station in the automated line. V magistrski nalogi je predstavljen postopek načrtovanja avtomatizirane linije za razstavljanje motorjev s trajnimi magneti iz električnih avtomobilov. Poudarek je bil na razvoju metodologije za učinkovito razstavljanje motorja in odstranjevanje magnetov iz rotorja. V prvem delu naloge je potreba po recikliranju motorjev opredeljena s potrebo po pridobivanju redkozemeljskih elementov kot kritičnih materialov. V tem delu sta predstavljena koncepta krožnega gospodarstva in urbanega rudarjenja kot glavna koncepta za trajnostno uporabo teh elementov v Evropski uniji. V drugem delu naloge je izvedeno ročno razstavljanje motorja iz električnega avtomobila Nissan Leaf in analiziran potencial pridobivanja redkozemeljskih elementov iz rotorja tega motorja s pomočjo pridobljenih magnetov. K procesu razstavljanja se je pristopilo sistematično, da bi opredelili vsak potreben korak, njegovo zahtevnost in čas izvedbe. Ugotovljeno je bilo, da je potreben korak razmagnetenja rotorja in da je ta korak najzahtevnejši glede časa in vložene električne energije. Ta analiza je služila kot osnova za načrtovanje avtomatizirane linije. V tretjem delu naloge so predstavljene zahteve za avtomatizirano linijo, ki izhajajo iz znanja, pridobljenega med ročnim razstavljanjem. Definiran je koncept avtomatizirane linije in ustvarjen digitalni model v programski opremi Siemens Plant Simulation. Na digitalnem modelu sta bili izvedeni dve simulaciji za potrditev izbire postaje za razmagnetenje v avtomatizirani liniji. circular economy rare earth elements permanent magnets electric vehicles PMSM motors Siemens Plant Simulation krožno gospodarstvo redki zemeljski elementi trajni magneti električna vozila PMSM motorji Siemens Plant Simulation true false false Angleški jezik Slovenski jezik Magistrsko delo/naloga 2025-09-15 15:05:10 2025-09-15 15:05:14 2025-11-13 12:56:56 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63179 257083651 Jeknic_Andrija_-_Nacrtovanje_avtomatizirane_linije_za_razstavljanje_sinhronskih_motorjev_s_trajn.pdf Jeknic_Andrija_-_Nacrtovanje_avtomatizirane_linije_za_razstavljanje_sinhronskih_motorjev_s_trajn.pdf 1 CF3E118EDDA39EA2A7557A50F4340F14 f123db554eeeabc9fd0d7965d181766d4b1d74bb7bffac4474aab8b89c86211f 734d7993-9234-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=217607 Fakulteta za elektrotehniko 0 0 0
