Abstract :
In the paper are being analyzed the magnetic losses that occur in the induction machines of low and medium power while being supplied by inverters realized with IGBT transistors. The analysis method is based on the over-position effect principle. As a working hypothesis is being neglected the saturation effect. During analyzes is being deduced the computing relations which allow the quality and quantity determination of the magnetic losses in the situation of the deforming supplying system. The theoretical results obtained using the computing program CALCMOT are back-up-ed by the experimental checks realized on two tri-phased induction motors with the powers: 0.37 [kW] /1500 [rpm], respectively 1.1 kW]/1500[rpm].
