Paragraph starter
The thermal management of the stator is a critical factor in achieving high power density in Axial Flux Permanent Magnet (AFPM) motors. Research indicates that strategies such as advanced channel cooling, immersion cooling, or the use of heat pipes can significantly mitigate heat buildup, thereby enabling higher current densities and improved torque output without risking demagnetization or component failure. The selection of an appropriate cooling method must be carefully considered in relation to the specific AFPM motor topology, as central stators in certain configurations present unique thermal challenges.
