Aircraft electric motor with integrated cooling system

An aircraft electric motor comprising:

• a motor unit having a rotor and a stator, wherein the stator includes a plurality of windings and cooling channels arranged to provide cooling to the plurality of windings;
• a drive unit configured to drive operation of the motor unit;
• and
• a cooling system comprising:
• a working fluid arranged within a cooling fluid flow path, wherein the cooling fluid flow path includes a liquid cooling path configured to direct flow of the working fluid through, at least, the cooling channels of the motor unit and a vapor cooling path configured to direct flow of the working fluid through the drive unit;
• a separator arranged upstream of each of the liquid cooling path and the vapor cooling path and configured to direct a liquid portion of the working fluid into the liquid cooling path and configured to direct a vapor portion of the working fluid into the vapor cooling path;
• and
• a mixer arranged along the cooling fluid flow path and configured to merge the flow of the liquid cooling path and the vapor cooling path at a location downstream of the motor unit and the drive unit.
