Rezumat: Lucrarea de fata prezinta o analiza a influentei infasurarii statorice asupra formei tensiunilor unui generator sincron pentafazat cu magneti permanenti. Sunt luate in considerare doua situatii: infasurare statorica avand bobine de tip concentrat respectiv distribuit si infasurare statorica plasata in crestaturi drepte respective inclinate. Studiul se bazeaza pe simulari ce utilizeaza metoda elementului finit (MEF) precum si pe incercari experimentale. Rezultatele obtinute arata o anumita superioritate a solutiei ce foloseste infasurari distribuite si crestaturi inclinate mai ales in ceea ce priveste riplul de cuplu dar si forma tensiunilor de linie si faza.

Cuvinte cheie: generator sincron pentafazat cu mgneti permnenti, analiza MEF.

Abstract: This paper presents a study on the influence of the stator winding upon the shape of the voltages of a five-phae permanent magnet synchronous generator. Two distinct structures are taken into discussion: stator winding with concentrated and distributed coils and magnetic circuit with straight and skewed slots. The sudy is based both on FEM simulations and experimental tests. The results prove a certain superiority of the solution that uses distributed coils and skewed slots mainly as regards the torque ripple but also the shape of the line and phase voltages

Keywords: five-phase permanent magnet synchronous generator, FEM analysis
