An electric hydraulic motor system for aircraft having a taxing and takeoff mode and a braking mode. While in the taxiing and takeoff mode, a battery and optionally other sources of energy stored within the aircraft together provide energy to drive an electric motor which in turn drives a hydraulic pump creating hydraulic pressure within the aircraft hydraulic system. The increase in hydraulic pressure within the system actuates a hydraulic motor connected to the aircraft wheels, thereby providing rotation to the wheels of the aircraft, moving the aircraft forward. Alternatively, while in the braking mode, the rotation of the wheels of the aircraft drive a second hydraulic pump which imparts an increase of the hydraulic pressure within the aircraft hydraulic system. The increase in hydraulic pressure within the aircraft hydraulic system drives a second hydraulic motor which drives an electric generator which simultaneously slows the aircraft and charges the aircraft battery.
