Simulation and Analysis of an Axial Flux Induction Machine

This paper presents an analytical and numerical evaluation of a single-stator, single rotor axial-flux induction prototype, with squirrel cage made of copper. Additionally a set of experimental test are carried out to validate those models. In order to estimate the magnetizing current required for the motor the Carter factor is calculated for different airgap lengths. Traditional equivalent circuit is used to compute operational conditions, based on parameters calculated by rotor locked and no-load tests parameters of a three-phase machine. Finite element analysis is used to verify the motor performance showing close agreement between them.
