Abstract
A drive system has at least two drive units each including a central shaft, a central gear wheel connected to the central shaft such that the central gear wheel rotates at a speed of the central shaft, and two to four decentralized gear wheels distributed over the circumference of the central gear wheel and meshing with the central gear wheel such that the speed of the central gear wheel is at least 0.5 times the speed of the decentralized gear wheels. The rotational speed of the central gear wheel is at least 0.5 times the rotational speed of the decentralized gear wheels. Each decentralized gear wheel is coupled directly and without transmission to a single electric machine, or to two electric machines of a plurality of electric machines. The central shafts of the drive units are coupled to form a series connection of the drive units.
