Heat-transfer improvements in an axial-flux permanent-magnet synchronous machine [PDF]
Applied Thermal Engineering, 2015 Axial-flux machines tend to have cooling difficulties since it is difficult to arrange continuous heat path between the stator stack and the frame. One important reason for this is that no shrink fitting of the stator is possible in an axial-flux machine. Using of liquid-cooled end shields does not alone solve this issue.

Comparative study of novel axial flux magnetically geared and conventional axial flux permanent magnet machines [PDF]
CES Transactions on Electrical Machines and Systems, 2018 In this paper, a performance comparison between the novel axial flux magnetically geared machines (AFMG) and the conventional axial flux YASA machine is presented. The AFMG and YASA machines have the same stator construction in which segments are equipped with concentrated windings to form the stator.
