The precise prediction of loses and the thermal analysis play an important role in improving the performances and efficiency of swiched reluctance motors. However, the calculation of SRM loses and temperature is especially complex due to the nonlinear magnetic characteristics with high frequency and saturaed fluxes. This paper describes the precise estimation and measurement method of the closses and temperature distribution in a 30 kW, 50,000 rpm switched reluctance machine. Firstly, a core los model was based on finite element analysis to determine flux waveforms. Measurement techniques were used to determine copper, core and mechanical losses. Secondly, those losses were applied to a thermal analysis model including a liquid stator cooling to calculate the temperature distributions in different materials of SRM. The results match with the data supplied by the manufacturer of the lamination steel. The objective of this SMR losses and thermal analysis method is a high speed of three phase 6/4 SMR. The experimental measurements were recorded by a data acquisition device. The temperature distribution was simulated 3D-FEA model. The tempererature rise at different points of the winding was also verified experimentally.
