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.

Cuvinte cheie: proiectare, analiza MEF, infasurare toroidala, masina de inductie bifazata


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.

Keywords: design, FEM analysis, toroidal winding, two-phase induction machine
