1) An overview of ANSYS-Maxwell software tool (environment philosophy, basic drawing tools, solver options, ...) 2) Choke calculation: Preparation of a parametric 3D model, setting of boundary conditions, adaptive and manual meshing, choice and setting of the solver. - Calculation of stationary magnetic field (constant current / current density load) - Calculation of non-stationary (harmonic) magnetic field (harmonic voltage / current load - demonstration of differences), calculation of losses in iron. 3) Choke calculation - continued: - Possibilities of using an external power circuit and the philosophy of using "dedicated elements". - Calculation of non-stationary magnetic field (transient task), Comparison with results from harmonic analysis, explanation of differences. 4) Using symmetry of geometry, sample of half, quarter and eighth symmetry, calculation of inductances and forces. 5) Transformer calculation (transient analysis): magnetic fluxes, induced voltage, calculation of self- and mutual-inductances. Comparison for sine and rectangular power supply. 6) Introducing RMXprt (environment philosophy, template overview, demonstration of options on a pre-prepared model) 7) Preparation of asynchronous motor model, calculation and extraction of simulation results 8) Export model to Maxwell (in full geometry and using symmetry), solver settings, calculation and basic postprocessing. 9) Preparation of a permanent magnet synchronous motor model (PMSM), calculation and extraction of simulation results 10) Export model to Maxwell (using symmetry), solver settings, calculation and basic postprocessing. 11) Individual work on given topic 12) Individual work on given topic 13) Presentation of results
