An electric aircraft lift motor with air cooling, the motor comprising:
- a stator connected to the electric aircraft, the stator comprising:
- an inner cylindrical surface and an outer cylindrical surface, wherein each of the inner cylindrical surface and the outer cylindrical surface is coaxial about an axis of rotation;
- and
- at least a cooling fin on the outer cylindrical surface of the stator;
- a rotor coaxial within the stator, the rotor comprising a rotor cylindrical surface and a rotor shaft defining the axis of rotation, wherein the rotor cylindrical surface and the inner cylindrical surface combine to form an air gap between the rotor cylindrical surface and the inner cylindrical surface, wherein the rotor comprises a magnet array positioned opposite to the inner cylindrical surface and spaced from the inner cylindrical surface by the air gap;
- and
- a first fan connected to an axial end of the rotor and configured to rotate with the rotor, the first fan comprising:
- a base platform and a roof platform, wherein the base platform is attached to the axial end of the rotor;
- and
- at least a blade configured to direct air toward the air gap, wherein the at least a blade is secured between the base platform and the roof platform.
A device for cooling a motor of an electric aircraft, the device comprising:
- a rotor configured to rotate around an axis of rotation, the rotor comprising:
- a rotor cylindrical surface;
- a rotor shaft defining the axis of rotation;
- a first axial end on one side of the rotor cylindrical surface;
- and
- a second axial end on the opposite side of the first axial end;
- a magnet array on the rotor, wherein the magnet array is positioned opposite to an inner cylindrical surface of a stator of the motor and spaced from the inner cylindrical surface by an air gap;
- at least a cooling fin on an outer cylindrical surface of the stator of the motor;
- and
- a fan connected to the first axial end of the rotor and configured to rotate with the rotor around the axis of rotation, the fan comprising:
- a first base platform and a first roof platform, wherein the first base platform is attached to the first axial end of the rotor;
- and
- at least a blade configured to direct air toward the air gap, wherein the at least a blade is secured between the first base platform and the first roof platform.
