Abstract

In this paper, an axial flux induction motor (AFIM) prototype with anisotropic rotor is presented and studied using analytical expressions in order to obtain steady state performance characteristics. The axial topology allows to develop high torque in low speed operation without the need of a gearbox, increasing the efficiency of the drive. This could represent a maj or advantage for the industry, in terms of the costs associated with its operation and reliability. The AFIM is analyzed by means of a multilayer model in Cartesian coordinates, where each layer represent a different region of the magnetic circuit. Poisson's and Laplace's equations are derived from Maxwell's equations and used to determine the induced currents of rotor, torque and efficiency. The proposed model considerer a power supply with voltage sources and the stator currents are calculated by means of the equivalent circuit which is previously determined by means of the multilayer model.
