The paper presents the methodology of determining the distribution of flux density in the magnetic circuit of a 3-phase axial flux machine with permanent magnets located on the rotor. It allowed to create an analytical dependences of the inductances and flux linkages. Particular attention was paid to such processing of mathematical model equations, so as to create a possibility to determine the machine properties in steady state on the basis of equations, without even having to use quantitative solutions. The theory of linear differential equations used here, with periodically variable coefficients, allowed to determine the Fourier spectra with respect to winding currents and electromagnetic torque in steady state operation.
