Summary

Purpose of the study subject is centered towards new calculation methods and methodology of the project at the power current electrotechnics specialized to the electric machines and devices. On the particular examples are the students apprised of creation of physical model, of entering important material properties and specific boundary conditions, of solution, of processing of caltulated data and their interpretation for a practical assimilation. These calculations are realized through the Method of Finite Elements (FEM ) aided by software equipment ANSYS.
