Abstract: An electric drive device includes a transmission with a first planetary gear set having a first element, a second element, and a third element. The transmission includes a second planetary gear set having a fourth element connected to the third element for conjoint rotation, a fifth element and a sixth element. A first output shaft is connected to the fifth element for conjoint rotation and a second output shaft is connected to the fourth element for conjoint rotation. A first electric machine has a first rotor that is or can be coupled to the sixth element such that torques provided by the first rotor can be introduced into the transmission via the sixth element.
