Rezumat: Au fost analizate posibilitatiile de realizare a unui generator sincron cu magneti permaneti si intrefier neted. S-a dovedit analitic, disparitia armonicilor de ordin superior din curba de variatie a inductiei magnetic atunci cand infasurarea statorica este amplasata direct pe miezul magnetic al generatorului.Utilizand metoda elementului finit au fost obtinute curbele de variatie a inductiei magnetice in intrefier precum si repartizarea liniilor de flux magnetic.

Abstract: The possibilities of elaborating a synchronous generator with permanent magnets and a smooth air gap had been analyzed. It was analytically proved that the harmonics of denture order disappear from the magnetic inductance curve if mounting the stator winding directly on the package yoke of the generator. The repartition of the magnetic flux lines and the curves of magnetic inductance variation inside the air gap are presented by applying the finite element method
