Abstract
Aspects of the subject disclosure relate to an electric motor that includes a stator and a rotor. The stator includes a stator body having a plurality of stator coil slots and a plurality of stator coils disposed respectively within the plurality of stator coil slots, each stator coil slot arranged a radially inner side of the stator body facing the rotor. The stator also includes a substrate mechanically coupled to the stator body and configured to receive a fluid via a manifold and distribute the fluid through a cavity formed between the substrate and the stator body. Each stator coil slot includes an opening forming a channel that extends longitudinally across the stator body for distributing the fluid through the channel and thermally interact with the plurality of stator coils and the stator body. Accordingly, the temperature of the electric motor can be regulated.
