Abstract

A method for using an electric motor as differential for a vehicle is disclosed. The electric motor for a hybrid or an electric vehicle is utilized in a split manner in order to provide both, the transmission and the differential required for operating a vehicle. The motor differential allows for rotating a pair of driving wheels at different speeds, mainly while turning of the vehicle. The split AC induction motor comprising of stator windings and two independent rotors is utilized to generate the flux and the torque required for running the vehicle as well as providing the differential action required for turning the vehicle.
