Abstract

Attention is paid to the popular FEMM (Finite Element Method Magnetics) program which is effective in the numerical calculations of the magnetic fields of electrical machines. The principles of the automated calculations providing the analysis of the dynamics of electromagnetic processes in turbo-generators are presented. This is realized in the form of a script on the algorithmic language Lua integrated with FEMM. The temporal functions of electromagnetic quantities are obtained by multi-position calculations of the magnetic field with ensuring its rotation together with the turbo-generator rotor. The developed program is universal in terms of the geometry and dimensions of turbo-generators, as well as the modes of their work with a minimum of input data in numerical form. This paper shows "extraction" of discrete temporal functions: the magnetic flux linkage of the phase stator winding; forces acting on the current-carrying and ferromagnetic elements of the structure; the magnetic induction at the fixed points; electromagnetic moment. This list can be expanded as part of the created program, as well as the use of the program can be extended to other types of electrical machines. The obtaining of a change period of any functions is provided by rotating the rotor to 60°.
