### A Mathematical Model of Axial Flux Disc Machines

#### Abstract

This paper describes a mathematical model to determine the equivalent circuit parameters of Axial Flux Disc Machines (AFDMs) of whatever configuration. Once fixed the dimensions of the machine (magnet width, winding lengths, axial thickness, etc.), the equivalent inductance and resistance and finally the current are calculated, for a generator operation mode. The model has been implemented in a software developed by the authors. The hypotheses at the base of the model have been verified through analyses performed with a conventional (FEM) method and the results of the simulations have been compared with experimental data, showing a satisfactory agreement. An AFDM-12 - a machine with a stator and two rotors, and one coil per pole and per phase - has been chosen for the analysis.
