Abstract

A motor gearbox assembly includes a gearbox housing that encloses a motor comprising a stator and a rotor, which is rotatable with respect to the stator. The rotor is rotatably mounted on a main power output shaft and is coupled to a first rotor pinion gear. The assembly further comprises a layshaft rotatably mounted in the gearbox housing outside of the motor, a first layshaft gear at a first axial end of the layshaft on a first side of the rotor and the stator, the first layshaft gear being engaged with the first rotor pinion gear and a second layshaft gear at a second axial end of the layshaft, the second axial end being on a second side of the rotor and the stator that is opposite the first side, the second layshaft gear being engaged with a power output gear coupled to the main power output shaft.
