For an axial flux permanent
3、magnet synchronous machine (PMSM) with a printed circuit board (PCB) stator winding, the temperature has great influence on the performance of the permanent magnet and FR-4, which is the material of PCB. An axial flux PMSM with PCB winding was studied. According to the heat transfer theory, a three-
4、dimension temperature field model was established. The finite element method (FEM) was used for the analysis and calculation of the temperature field. Heating and temperature of each component was studied. A prototype machine was manufactured and experiments were conducted to test the thermal perfor
5、mance. The impact of increasing the contact area between the frame and the PCB stator on the temperature field was analyzed and the temperature rise was optimized, which could provide some reference for the research on the cooling approach.
