La transizione verso soluzioni di trasporto più sostenibili ha guadagnato un significativo slancio negli ultimi anni, con i veicoli elettrici (EV) che stanno emergendo come un'alternativa promettente ai veicoli tradizionali con motore a combustione interna. Un elemento fondamentale che guida il successo e l'adozione degli EV è il motore elettrico, una componente chiave che svolge un ruolo cruciale nel determinare le prestazioni, l'efficienza e il costo complessivo del veicolo. Lo scopo di questa tesi è approfondire lo sviluppo, il potenziale e le implicazioni dei motori elettrici a basso costo per i veicoli elettrici, fornendo un'analisi e un confronto completi con i motori convenzionalmente utilizzati. I motori elettrici sono il cuore dei veicoli elettrici, convertendo l'energia elettrica della batteria in energia meccanica per muovere il veicolo. Tuttavia, il costo dei motori elettrici è stato un fattore significativo che ha ostacolato l'adozione diffusa degli EV. Questo studio mira a affrontare questa sfida investigando la fattibilità dello sviluppo di motori elettrici a basso costo che mantengano elevati standard di prestazione. Comprendere i fattori chiave che influenzano i costi dei motori ed esplorare approcci innovativi di progettazione e produzione può contribuire a rendere i veicoli elettrici più economicamente accessibili ai consumatori. La tesi si propone di esplorare l'intricato rapporto tra costo e prestazioni all'interno della tecnologia dei motori elettrici. Attraverso un esame approfondito delle innovazioni costruttive e progettuali, la ricerca mira a individuare strategie per ridurre i costi utilizzando soluzioni senza magneti o a basso contenuto di magneti, mantenendo al contempo metriche di prestazione ottimali del motore. L'indagine su vari aspetti della tecnologia dei motori elettrici prevede di fare luce su come i progressi nei materiali e nel design possano simultaneamente ridurre le spese di produzione e iv migliorare l'efficienza. Inoltre, la tesi condurrà un'analisi comparativa con i motori tradizionali dei veicoli, evidenziando i benefici economici e i potenziali svantaggi associati all'adozione di motori elettrici a basso costo. Questa indagine completa intende fornire preziose intuizioni sull'equilibrio delicato tra considerazioni di costo e prestazioni ottimali, fondamentale per guidare lo sviluppo e l'adozione diffusa di tecnologie per veicoli elettrici economicamente sostenibili. Inoltre, lo studio si impegna a valutare le implicazioni dell'adozione diffusa di motori elettrici a basso costo per i veicoli elettrici, considerando l'impatto ambientale, l'efficienza energetica e la sostenibilità complessiva nella mobilità elettrica. Contribuendo a fornire intuizioni sulla fattibilità e i vantaggi dei motori elettrici a basso costo, la ricerca mira ad accelerare la transizione verso la mobilità elettrica e a mitigare le emissioni di gas serra legate al trasporto convenzionale. In conclusione, questa tesi rappresenta un contributo significativo al settore dei veicoli elettrici affrontando la componente critica del motore elettrico, aprendo la strada a un futuro più sostenibile ed economicamente sostenibile nella mobilità elettrica.
