Abstract
A propulsion system for an electric vehicle includes a first electric propulsion motor including a stator and a rotor that has a first and second output shafts that are axially opposed and define first and second torque outputs of the first electric motor. The system also includes a second electric propulsion motor including a stator and a rotor having a second output shaft with a torque output. Further, the system includes a first reduction gearbox to receive the torque supplied on the first torque output of the first electric motor where appropriate via a first selective or non-selective coupling system, a second reduction gearbox to receive the torque supplied by the second electric motor where appropriate via a second selective or non-selective coupling system, and a third coupling system for coupling the second torque output of the first electric motor to the torque output of the second electric motor.
