Resumen
Within the framework of an electrical drive, application of a microprocessor technique requires of design engineers an utilization achievements in various fields, among others the mathematical theory of structures and algorithms, the theory of transformations and minimization.
In this paper, problems of minimization of the structure of the dynamic mathematical model of an electrical three-phase induction motor with asymmetry of the stator and rotor circuit are analyzed : Equations of the induction machine in the natural system have been transformed to the zero-sequence system and the two-phase system connected with the coordinate system rotating in general with any speed in relation to the stator. The method of choice of the speed of the coordinate system is given in order to get the simplest form (minimization problems) of equations of the mathematical model for the symmetrical state and various asymmetries of the three-phase induction machine.
