Popovich A. Mathematical models, parameters and characteristics of asynchronous motors electromechatronics systems.

The object of research: processes in the asynchronous motors in structure of electromechatronics systems. The dissertation purpose: evolution of the theory of asynchronous machines of electromechatronics systems, to the new development and to the developments of existing methods and mathematical models, including in view of change of parameters according to a mode of operation, with perfection of means of integral criterion of efficiency. Efficiency improves owing to use created effective mathematical and software of complex research and designing. The Methods of research: numerical methods for solving systems of differential equations, approximation methods, solutions of the electromagnetic field, the method of spatial systems, the theory of reactive power on the Fryze developed a method equivalenting 3-D field model of AD chain model. Theoretical and practical results and innovation: the theory of asynchronous machines which are components of electromechatronics systems has been developed. Thus are considered: structure of winding parts of the stator, the plan of their associations among themselves and with exterior devices, asymmetry and nonlinearity of parameters, allocation in space and in a time not under the law of a sine, property of integration of winding parts of the stator in system of model operation. The method is developed for the replacement model of field by chain model with two-dimensional non-linear parameters in view of agency of space harmonics that ensures model operation of modes of operation with exactitude of field method and fast operation of chain method. Expressions for definition of electrical power factor in conditions of asymmetry, not under the sine law of processes, dynamic modes of operation have been developed. Degree of introduction: in the form of mathematical models of their software implementations, in a research institute, in the educational process. Sphere of use: at manufacturing plants of asynchronous machines in the research and design organizations that develop electromechatronics systems which include asynchronous machines, in the educational process.
