In aceasta lucrare s-a avut in vedere analiza energetica a sistemului de actionare cu motor asincron cu
considerarea pierderilor in fier si convertor static cu modulatie sinusoidala. Modelul global al sistemului de actionare,
realizat în mediul de programare MATLAB-Simulink, furnizeaza toate marimile necesare pentru calcularea indicatorilor
energetici. Pentru obtinerea acestora s-a simulat functionarea intr-un punct static de functionare. Algoritmul de calcul in
vederea obtinerii analizei energetice parcurge si un proces iterativ pentru obtinerea valoriilor rezistentei si inductivitatii de
magnetizare.

Abstract
This paper had in view the energetic analysis of the drive system with induction motor and static PWM
sinusoidal converter, by taking into account the iron losses. The global model of the drive system was realized in MATLABSimulink
software and gives all necessary facilities for calculate the quality indicators. To determining them, the operation
of the system was simulated for each operating point. The calculation algorithm contains an iterative process for the
magnetization resistance and inductance obtaining.
