The paper deals with main effects occurring in flux linkages of the stator winding and analogous effects occurring in magnetising currents of induction motors whose rotor cores have certain anisotropic properties. Analytical forms which define spectra of the flux linkages have been provided on the basis of approximation of the magnetic field co-energy function. In the paper a series approximating the symmetrical components of phase flux linkages was derived and interpreted. Results of field calculations, carried out for the cores, were used to determine the influence of the anisotropy on the co-energy function of the rotating magnetic field and functions of the flux linked with the winding.
