Abstract
This paper presents different oil cooling configurations with possibility to be used in electrical machines designed and developed for e-mobility application. Focus in this paper part is placed on the stator cooling. Different cooling solution based on the cooling channels in the lamination, windcap, and sleeve are presented and discussed. The proposed configurations are evaluated using transient fluid flow simulations and a comparison in results is presented. Additionally, simulation results are evaluated and verified using measurements on a 3D printed prototype.
