The object of research: electromagnetic processes in active volume of hybrid excited synchronous generator. The purpose of research: establishment the regularities of electromechanical energy conversion processes in axial flux hybrid excited generator to substantiate their constructive relations and depth of output voltage regulation. Methods of research: The solution of the set tasks was carried out using the general theory of electric machines, structural-system approach, system and genetic modeling of electromechanical structures and known methods of calculation of permanent magnet generators, mathematical modeling, the basis of which is the numerical methods for solving differential equations of the electromagnetic field in an electric machine using the finite element method, methods of experiment planning theory and physical modeling of electromagnetic fields. Theoretical and practical results and innovations: An important scientific and practical problem for electrical engineering has been solved to substantiate the parameters of a synchronous generator with hybrid excitation and axial magnetic flux. The geometrical relationships between the active parts of the machine are determined and the basic regularities of electromechanical energy conversion in them are established. The analysis of steady-state and transient modes of operation of machines with the help of the developed mathematical models allows to increase the efficiency of control of the magnetic flux. A subject degree of introduction: the main results of the work were implemented at the Institute of Renewable Energy of the National Academy of Sciences of Ukraine and in the laboratory of "SKB of Electromechanical Systems" of the National University "Lviv Polytechnic" MES of Ukraine. Effectiveness of implantation: the results obtained were implemented in the design of new wind and hydro generators with improved performance and in the study of complex models of electric vehicles when creating machines with an increased speed control range. Sphere of use: electric engineering, autonomous energy.
