COAXIAL CONTRA-ROTATING MOTORS FOR DIFFERENTIAL LANDING GEAR STEERING

摘要

A landing gear for an aircraft has a pair of spaced wheels, and a drive and steering arrangement operable to drive each of the wheels in either rotational direction. The drive and steering arrangement includes two permanent magnet rotors, with each of the permanent magnet rotors connected to rotate with one of the wheels. A single stator is positioned to drive both of the rotors. The drive and steering arrangement is mounted between the pair of wheels.
