N2 - This paper describes an analytical simpliïcation method for the explicit calculation of the time- dependent thermal behaviour of an electrical machine obtained by a Lumped Parameter Thermal Network (LPTN). This method builds up on the T-sum rule, which was introduced by Kuhn for the application in control theory. Therefore, advantage is taken of the speciïc shape of the equation system obtained by nodal analysis. Finally, the presented method is applied to an air-cooled multiphase synchronous machine with surface-mounted permanent magnets (SM-PMSM) for mobile applications, calculating the temperature response of a step function and a load proïle. The solution of the presented method is compared with the numerical solution of LPTN and Finite Element Analysis (FEA), proving the possibility for the fast calculation of thermal behaviour of electrical machines.
