Thermal management for stator cooling in electric machine

An electric machine having a thermal management system and for use in an electrified vehicle, the electric machine including a rotor, a stator and a housing, the electric machine comprising:

• an oil feed channel at least partly positioned in the housing and configured to provide cooling oil to at least the stator;
• the stator including:
• a stator teeth region and a stator yoke region, the stator teeth region being proximate teeth of the stator and positioned radially inward of the stator yoke region,
• a plurality of first axial channels in the stator yoke region extending axially through the stator substantially from a first axial end to an opposed second axial end,
• a plurality of second axial channels in the stator teeth region extending axially through the stator substantially from the first axial end to the second axial end, the second axial channels being proximate the stator teeth and positioned radially inboard from the first axial channels, and
• at least one cross-bridge radial channel extending between and connecting a pair of radially opposed first and second axial channels of the plurality of first and second axial channels;
• wherein the electric machine is configured to receive the cooling oil into the first and second plurality of axial channels such that the cooling oil flows axially and radially within the stator to cool at least the stator.
