“…The most expedient approach when determining electromagnetic energy is the method based on electromechanical transformation of energy. In special electric drives, parameters of instant effort and the moment on a shaft of the device [15] will allow one to define knowledge of electrical power processes quite precisely that is now quite a difficult task without the corresponding experimental adjustment [16][17].…”

In the article the research of electrical power processes is made for optimum modeling and design of special electric drives with asynchronous motors. For creation of various types of electric drives with optimum mass dimensional and power indicators, it is necessary to define precisely values of electric currents windings, the electromotive forces and the corresponding flux linkage in the stator and a rotor of components of the research devices. The main difficulty in the research and determination of parameters is continuous change of these sizes in a consequence of change of electric parameters of the feeding system of tension, the spatial provision of mobile parts of the drive relatively motionless parts and features of the technological process. It leads to change of interposition of axes of the field of the stator and a rotor, phase angles of shift of electric currents and the electromotive forces of components of special electric drives. The research of electrical power processes with use of the methods based on electromechanical transformation of energy allows determining required parameters quite precisely. Determination of value of the savedup energy will allow one to model and design quite precisely without the corresponding experimental adjustment special electric drives. And this approach allows one to determine power parameters at any moment that gives the chance to define instant values of required parameters, including instant values of force and the moment on a shaft of the electric drive. Exact and correct definition of power ratios in the research electric drives will allow one not only to carry out optimum design, but also to create optimum control systems of electric drives taking into account technological features of concrete production.Keywords-special electric drive, the operated asynchronous cascade electric drive, energy transformation, mathematical modelling, the electromagnetic field, electromagnetic system.

Problems of optimization of special electrical and electromechanical systems in modeling, creation and design are solved mainly by methods of mathematical programming. The task of mathematical programming is to find extremes of the function of many variables in the presence of restrictions on variables, which creates fundamental difficulties. To solve such problems, the number of methods for solving the general problem of mathematical programming is currently expanding significantly. In this regard, the trend in the development of mathematical programming is following the path of highlighting and studying various subclasses of problems. The use of certain specific features of the tasks of the selected subclass creates opportunities for their more effective investigation and solution. Examples of such subclasses give convex, quadratic, linear programming problems, transport-type problems, and others. Geometric programming is also a section of mathematical programming that research a certain class of optimization problems. However, when using geometric programming, you have to apply linear, nonlinear programming, the concept of convex programming. Using optimization methods will allow you to correctly investigate, design and create special electric drives.
