Operation Characteristics of Low Power Asynchronous Motors Supplied by Static Converters

In the paper there is carried out a thorough study of drives with asynchronous motors supplied by voltage and frequency static converters. A lot of simulations are presented, emphasizing the distorting regime effects, both in the supply network and in the asynchronous motor. The mathematical model used makes also possible an energetic balance sheet. The results and simulations carried out consider the magnetic saturation on the path of the main and leakage field of the slots. The researches carried out with an asynchronous motor rated at 1.5 kW, supplied by a static converter have emphasized that the errors do not exceed 2.2% between the simulated quantities and the quantities determined experimentally. These results justify the research carried out, which provides correct qualitative and quantitative simulations for the steady state.
