High power density electric motors are essential for the electrification of aircraft. Use of a segmented stator, which makes the winding process easier and allows a higher slot fill factor, can help increase the power density as well as the efficiency of a motor. The cooling for the segmented stator can be done using a cooling jacket. In this paper, three different designs are presented. Two designs use the compression sleeve that provides the mechanical support to the stator as the cooling jacket, with radial or axial fins built in. One has a dedicated cooling jacket on top of the sleeve. A numerical study was performed on the three designs. All three have similar cooling capability, with the dedicated cooling jacket having a slight advantage, but it also results in a much higher pressure drop and requires more pumping power to achieve the low resistance.
