Abstract: The temperature of axial-flux permanent magnet couplers was analyzed using the electromagnetic-thermal coupling method. On the basis of analytical magnetic field calculation， a magnetic field analytical model of the axial-flux permanent magnet couplers was presented to derive the eddy current loss formula. The thermal resistance and heat transfer coefficient were calculated， and a thermal model of axial-flux permanent magnet couplers was established by taking the eddy current loss as the heat source. The electromagnetic-thermal coupling method was analyzed to predict the effect of various loads on eddy current loss and copper plate temperature rise. The analytical results compared with the finite element results showed that the magnetic field analytical model and the thermal model of axial-flux permanent magnet couplers using electromagnetic-thermal coupling method could predict the eddy current loss and the copper plate temperature rise reasonably and quickly.
