Abstract
An integral motor and wheel assembly for aircraft landing gear is provided that includes an electric motor packaged within at least one gear wheel and configured to fit completely within the space provided in an existing aircraft for the landing gear components. The motor is positioned within the wheel to minimize the spin-up weight and to maximize the space within a given volume allocated for the motor. Installation of this motor and gear wheel assembly in an existing aircraft landing gear is designed to permit the continued use of existing landing gear components, including tires, axles, and pistons, so that the assembly can be easily retrofitted into existing aircraft.
