To the Question of Development of the Universal Model of a Three-Phase Electric Motor with the use of Computer Simulation Tools

Results of development and realization of mathematical model of three-phase asynchronous electric motor with a squirrel-cage rotor are considered in this article. The peculiarity of the considered mathematical model is to provide the possibility of organizing the power supply of the stator windings of the electric motor from various sources, including, non-sinusoidal output voltages, as well as for various unbalanced voltages on each of the stator windings. It is possible to study the characteristics of asynchronous electric motors on the basis of the obtained model, while the accuracy tests are not inferior to the results of experimental studies. The mathematical model of the electric motor is realized in the environment of computer simulation Matlab Simulink, the detailed compilation of this model in blocks and their interrelation is shown. The adequacy of the developed model is verified by comparing the results obtained with the characteristics constructed using the known electric motor model.
