Abstract

This paper presents a detailed investigation of AC copper losses in high-speed high-power density permanent magnet synchronous machine. For parallel strands winding, it is not easy to accurately estimate the AC copper losses using finite element model (FEM), due to the random distribution of the conductors inside the slots. Therefore, this work is focused on the separation of the AC copper losses component from the total measured losses. In order to obtain more precise results, the effect of manufacturing process on the stator core has also been considered. A 3D FEM has been used to evaluate the total power losses including the effect of the end-windings. Finally, the influence of the temperature on the AC losses is taken into account by monitoring the winding temperature during the experiments.
