description: The subject of the graduate qualification work is âComparative analysis of the calculation of reactive EMF in DC machines by analytical and numerical methodsâ. The given work is devoted to verification calculation of a DC machine 4PF132S with a rated power of 10 kW and analysis of its reactive EMF with variations in the geometry of the armature slot. The calculation of reactive EMF was carried out in two ways: analytical (the method of conductivity of the groove) and by numerical simulation in the QuickField program. A comparative analysis of the results was done. The work was fulfilled on the basis of the Higher School of Electric Power Systems in the laboratory of electrical machines. It was found that it is possible to increase efficiency by 2%. Due to the fact that the magnetic system was a bit overpriced. It is established that reactive EMFs may have discrepancies.
