Beschreibung
Zusammenfassung:	The invention relates to an electric drive comprising - a motor arrangement (10) with a plurality of electric machines (12), - an output arrangement, and - a reduction stage which is connected to the motor arrangement (10) on one side and to the output arrangement on the other side, comprising a reduction sun (34) connected to the output arrangement and a plurality of reduction planets (28), each of which is connected to one of the electric machines (12) and which are arranged around the reduction sun (34) in an annular manner and rotate on the sun so as to transmit a torque. The invention is characterized in that - the reduction stage has a rotatably mounted reduction ring gear (30) on which the reduction planets (28) rotate so as to transmit a torque, and - the output arrangement has a summation stage (50) which is designed as a Ravineaux-type set with a summation ring gear (52) fixed to the housing, with a summation carrier (54) on which two summation planet (56, 56') sets that mesh with each other are rot
