The paper presents analyses of an inductor motor with axial excitation flux. To reduce overall dimensions of an electric machine and increase its efficiency, the stator winding is coiled with tooth pitch and excitation flux is performed by the annular magnet. To increase the torque, the winding is implemented as separated phase zones, rotor slots and stator elementary slots are filled with solid insulator and the air gap is filled with magnetic liquid. The electromechanical model of the inductor motor was designed in the basis of modified discrete Rademakher functions, methods of equivalent conductance and symmetrical components. The results of the study are the system of equations that describes self-inductance and mutual inductance parameters, electrical equilibrium and torque equations. The analysis of the torque equations shows, that a motor of the axial type has the same torque as a radial excitation motor or a reluctance motor. At the same time electrical losses of the inductor motor with axial excitation flux has electrical losses three times less than radial excitation one.
