Abstract

An electric drive includes a motor configuration with a plurality of electric machines, an output configuration, and a transmission stage. The output configuration has a summing stage configured as a Ravigneaux set with a summing internal gear, a summing spider, two sets of summing planets, and two summing suns. The transmission stage has a transmission sun, transmission planets, and a rotatably mounted transmission internal gear. The transmission sun is connected to the output configuration. The transmission planets are each connected to a respective one of the electric machines. The transmission planets roll on the transmission sun and on the transmission internal gear in a torque-transmitting manner. The transmission internal gear is fixedly connected to one of the two summing suns. The transmission sun is fixedly connected to another one of the two summing suns. A drive configuration for a motor vehicle is also provided.
