摘要：
A 3D analytical thermal model of axial flux permanent magnet synchronous machines is developed. It consists in subdividing the machine geometry into small volumes that are considered to be homogeneous and isotherm. Heat capacities and thermal conductivities are deduced from experience and finite volume method calculations (COSMOSFloWorks (R)). Heat capacities and heat transfer coefficients are temperature-dependent, as losses are. This feature is taken into account in the integration of the differential equation system governing the thermal behaviour of the machine in such a manner that it decreases simulation time. This resolution allows a fast computation of the machine's thermal behaviour and to predict its design's feasibility.
