Rezumat: 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.

Keywords: energetic analysis, induction motor, sinusoidal PWM modulation
