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.
