### Mathematical Model for Parametric Analysis of Axial Flux Disc Machines

#### Abstract

In the paper a parametric analysis of Axial Flux Disc Machines (AFDMs) is performed in order to calculate the Total Harmonic Distortion (THD) of output voltage as a function of the configuration and size of permanent magnets. THD is an important issue, for instance, in renewable energy applications of AFDM (wind generators) and the proposed simulation model can be used to predict the THD of a machine on the basis of key parameters. A mathematical model has been developed to determine the equivalent circuit parameters of AFDMs of whatever configuration. Then, the equivalent inductance and resistance and the current are calculated, for a generator operation mode. The model has been validated by means of experimental data. Finally, it has been used to perform parametrical analyses on an AFDM-12 - a machine with a stator and two rotors, and one coil per pole and per phase – with different position and size of trapezoidal magnets.
