Abstract
Definisan je metod za određivanje prostornih vektora struje rotora asinhronih mašina sa kaveznim namotajem, kao i metod za proračun fazora fluksnih obuhvata i struja rotora i statora. Uvedena je strujni fluksni obuhvat, koji pojednostavljulje postupak  određivanja fazora fluksnih obuhvata. Definisan je metod za proračun induktivnosti i otpornosti T ekvivalentne šeme asinhronih mašina. Definisan je metod za proračun komponenata momenta, koje potiču od visokih prostornih harmonika struje, kao i pravilo za proračun rezultantnog momenta na osnovu harmoničkih komponenata momenta.
Method for determination of space vectors of currents in induction motors with squirrel cage, and a method for calculation phasors of flux linkages and currents of rotor and stator are determined. Current-flux linkage is introduced, which simplifies determination of phasors of flux linkages. Methods for calculation of inductances and resistances of T equivalent circuit for induction motors are defined. A method for calculation of components of torque, which originate from high space harmonics of currents, and rules for calculation resultant torque on the basis of harmonic components of torque are determined.
