Abstract

A drive system for a motor vehicle includes a drive shaft with a flywheel mass arrangement provided thereon, an electric machine for driving the drive shaft and/or obtaining electric energy from the rotating drive shaft. The electric machine has a stator arrangement and a rotor arrangement which can be rotated by the drive shaft. The rotor arrangement is connected via the flywheel mass arrangement to the drive shaft. Furthermore, the rotor arrangement is connected to the flywheel mass arrangement via a connecting region having a higher resistance to thermal conduction than at least one of the regions that adjoins the connecting region.
