New approaches to the formulation and solution of problems of parametric synthesis of electric machines of new designs with a concentrated electric and distributed magnetic system are shown. The methods of designing and synthesizing traditional electric machines were mainly focused on machines containing distributed electric stator windings with a concentrated magnetic system. A distinctive feature of generators of the axial-radial configuration is the concentrated electric windings with a distributed magnetic system. As a result, the development of methods for parametric synthesis of machines of new designs refers to the solution of urgent problems. As a result of the analysis of the design stages of new generators, a complex method of parametric synthesis has been developed. At the first stage, a mathematical model of the generator is used, on the basis of which an automated program for its calculation is developed. It implements synthesis based on an incomplete data set, in the direction from electromagnetic loads to the size of the machine. At the second stage, numerical experiments are performed using a mathematical model of the generator, with the determination of the optimization parameter. The calculation is performed according to the matrix of a full-factor experiment, compiled on the basis of the theory of planning experiments. As a result, the range of variation of electromagnetic loads is found, which is close to optimal. At the third stage, statistical processing of the results of numerical experiments, determination of significant factors, and regression analysis with the construction of an optimization model are carried out. The fourth stage is implemented using an optimization procedure based on the Box - Wilson gradient method. It allows you to find an even narrower zone of variation of significant factors, under which the optimization parameter satisfies the specified conditions. The use of complex parametric synthesis makes it possible to significantly reduce the mass of the designed electric machines of new designs in comparison with drum-type inductor machines of the same power. The presented procedure for the complex synthesis and optimization of generators with a concentrated electric and distributed magnetic system will be useful for researchers and designers who do not have sufficient experience in developing machines of such structures.
