Abstract

Empiric analytical expressions based on CFD are used in this work to define the convective heat coefficient in different parts of an axial flux permanent magnet machine having yokeless and segmented armature topology. Thermal simulations are carried out for the stator and rotor individually, where only a segment needs to be modelled due to thermal periodicity. Electromagnetic simulations using a multilayer 2D model are used to evaluate the electromagnetic losses in the machine. The accuracy of the coupled modelling technique was validated on a preliminary prototype.
