The use of an electric vehicle powertrain with distributed motors and electric differential offers new design options and high dynamic behaviour of the vehicle. Two design concepts with two squirrel-cage and doubly-fed induction motors, respectively, are evaluated and compared. A qualitative validation is presented and conceptual differences in the energy flows within the powertrains are reviewed and simulated. Both concepts prove to be applicable in general. Speed synchronisation problems of the motors can be effectively reduced with the doubly-fed induction machine concept.
