Abstract
A drive system has at least one drive unit each drive unit including a central shaft and a central gear connected to the central shaft such that the central gear rotates at a speed of the central shaft. Two to four decentralized gears are distributed around the circumference of the central gear and mesh with the central gear such that the rotational speed of the central gear is at least 0.5 times the rotational speed of the decentralized gears. A plurality of electric machines are operable at a speed of at least 4,000 rpm, and each decentralized gear wheel is coupled directly and without transmission ratio to a single electric machine or to two electric machines, respectively.
