Claim 11:
12. A vehicle comprising:
an electric propulsion system; and
a battery;
wherein the electric propulsion system comprises:
a motor drive coupled to the battery;
an electric motor coupled to the motor drive, wherein the motor drive and the electric motor are housed within a housing;
a manifold-mini-channel heat sink (MMHS) integrated into the housing, wherein the MMHS comprises:
an inlet manifold having a plurality of air inlets formed in a front of the housing, wherein an air inlet in the plurality of air inlets is respectively coupled to an inlet air passage in a plurality of inlet air passages;
a set of plurality of circumferentially grooved micro-channels formed in the housing and coupled to the air inlets and conductively thermally coupled to stator windings of the electric motor; and
an outlet manifold having a plurality of air outlets formed at a back of the housing and coupled to the set of plurality of circumferentially grooved micro-channels, wherein an air outlet in the plurality of air outlets is respectively coupled to an outlet air passage in a plurality of outlet air passages, wherein the set of the plurality of circumferentially grooved micro-channels connects each inlet air passage in the plurality of inlet air passages to an adjacent outlet air passage in the plurality of outlet air passages;

the electric motor comprising Pseudo-Edge Wound (PEW) stator windings configured to provide a low thermal resistance path from a stator of the electric motor to the housing;
a high temperature tolerant thermally conductive electrical insulator coating the PEW stator windings.
