Abstract
In this paper a Lumped Parameter Thermal Network (LPTN) is proposed for a Yokeless and Segmented Armature (YASA) axial flux permanent magnet (AFPM) machine. A simulation model is used to examine the machine in isolation, with an Integrated Motor Drive (IMD), and the machine and IMD with a remote heat sink connected using heat pipes. Losses from electrical and magnetic Finite Element Modelling (FEM) are used as inputs to the model. Introduction of the IMD is found to reduce the power rating of the machine by 27%. This performance can be returned by utilising a remote heat sink configuration to enable enlargement of the heat sink by twice the original volume.
