Heat Guides Fabricated Using Additive Manufacturing for Enhanced Heat Transfer in Next Generation Electrical Motors
HEATGEM aims to investigate a new heat extraction approach in application to electrical machines. The proposed technique employs thermally conductive heat guides (TCHGs) to provide supplementary heat evacuation paths for the electric machine (motor/generator). The goal is that the optimized TCHGs allow for a 30% improvement in dissipative heat transfer from the winding body and insignificant additional power loss, for the analysed stator-winding assembly. The research is focussed on the stator winding assembly where the main sources of the heat are located, the heat dissipated from the engine being one of the most important problems to be solved. The TCHGs rely on conductive heat transfer. It is intended for the TCHGs to be an integral part of the stator-winding assembly.
