Zusammenfassung:
Electric drives in aviation have high requirements in terms of specific power and reliability. Flux barriers in the stator can influence both the electro-magnetic properties and the cooling of the electrical machine. A procedure is presented with which the efficiency of the cooling concept in these flux barriers is determined. For this purpose, three different geometries were compared with each other in terms of their cooling performance and the resulting pressure loss. The use of fins and pins in the flux barrier lowers the hotspot temperature in the stator slot by more than 10K in comparison to a blank flux barrier and enables comparable temperatures to be achieved as with cooling jacket cooling. The pin geometry leads to the lowest hotspot temperatures but increases the pressure loss across the flux barrier and the manufacturing effort.
