A detailed analysis of cogging torque components reveals that besides well-known native cogging torque components exist also additional cogging torque components which are provoked by assembly tolerances in mass–production. A finite element method and Fast Fourier transform were used to study and analyse a model of PMSM which enables simulation of manufacturing tolerances and assembly imperfections of rotor permanent magnets. Calculations confirmed that imprecisions in mass–production cause the phenomena of additional cogging torque harmonic components, which are not present in the case of a perfectly assembled motor.

W artykule przestawiono analizę czynników wpływających na pojawienie się momentu zaczepowego w maszynie PMSM. Analizy metodą elementów skończonych oraz szybką transformatą Fouriera, przeprowadzone na modelu maszyny pozwoliły na wykonanie symulacji momentu zaczepowego i wpływu jaki mają na jego składniki stopnie tolerancji na etapie produkcji maszyny.
