1. An aircraft electric motor comprising:
a cooling system comprising an annular heat exchanger;
a motor housing arranged radially inward from the heat exchanger, the motor housing having an outer wall and an inner wall, wherein a rotor-stator cavity is defined radially between the outer wall and the inner wall and a gear assembly cavity defined radially inward from the inner wall;
an annular rotor sleeve arranged within the rotor-stator cavity, the rotor sleeve having an inner diameter wall, a connecting wall, and an outer diameter wall, wherein the inner diameter wall, the connecting wall, and the outer diameter wall define a compounded curvature, U-shaped channel configured to receive a U-shaped magnet structure and a sleeve inner cavity defined radially inward from the inner diameter wall, wherein the inner wall of the motor housing is arranged radially inward from the inner diameter wall of the rotor sleeve;
a gear assembly arranged within the gear assembly cavity;
a first shaft operably coupled to the rotor sleeve and configured to be rotationally driven by the rotor sleeve to drive rotation of a portion of the gear assembly; and
a second shaft operably coupled to the gear assembly and configured to be rotationally driven by the gear assembly.
