Questa tesi presenta la progettazione di un motore sincrono a magneti permanenti (PMSM) con rotore interno a forma di V, con slot frazionati, avvolgimento concentrato e doppio strato, per applicazioni in pompe dell'olio automobilistiche. Include una revisione completa dei tipi di PMSM, dei materiali, delle perdite, dei layout degli avvolgimenti e confronta gli avvolgimenti distribuiti con quelli concentrati. Lo studio esplora anche gli effetti del numero di slot/poli e identifica le principali fonti di rumore all'interno della macchina. Il processo di progettazione segue un approccio preliminare passo-passo utilizzando equazioni analitiche, con analisi e verifica condotte tramite il Metodo degli Elementi Finiti (FEM) nel software Altair Flux Motor. L'ottimizzazione del motore viene raggiunta regolando le dimensioni dei magneti e gli angoli dei poli magnetici. Infine, la tesi fornisce la curva caratteristica coppia-velocità e la mappa di efficienza nell'intervallo coppia-velocità.

Abstract
This Project details the design of an interior rotor V-shaped, fractional-slot, concentrated winding, double-layer permanent magnet synchronous motor (PMSM) specifically for automotive oil pump applications. It includes an in-depth review of various PMSM types, the materials used, sources of losses, and different winding configurations. A comparison between distributed and concentrated windings is also provided. The study delves into the impact of slot/pole combinations and identifies the primary noise sources within the motor. The design methodology involves a step-by-step preliminary approach utilizing analytical equations, with subsequent analysis and validation performed through the Finite Element Method (FEM) using Altair Flux Motor software. Motor optimization is achieved by first, fine-tuning the dimensions of the magnets and the angles of the magnet poles. Second, by changing slot dimensions. Ultimately, the thesis presents the torque-speed characteristic curve and an efficiency map across the entire torque-speed range.File | Dimensione | Formato | |
