Rezumat
In aceasta lucrare se propune o solutie originala in scopul ameliorarii performantelor masinii asincrone bifazate,prin eliminarea armonicii spatiale de ordinul trei din spectrul campului din intrefier. In acest scop, este utilizata tehnica infasurarii in inel si o metoda de repartizare a bobinelor in crestaturi. Simularile bazate pe MEF, precum si incercarile
experimentale demonstreaza superioritatea acestei solutii propuse asupra performantelor masinii bifazate "clasice",precum si asupra masinii de inductie trifazate.

Abstract
This paper advances an original solution for the improvement of the two-phase induction machine performance
by eliminating the third order harmonic from the air-gap magnetic field spectrum. For this purpose, toroidal coils are used
and a special placement in the stator slots is designed. The fem based simulations and the experimental tests prove the superiority of this solution over the „classic” two-phase machine performance as well as over the three-phase machine.
