Drive system and drive unit

Abstract

The present invention relates to a drive device and a drive unit comprising the drive device. A drive device (2) comprises an electric rotary machine (10) and a frame (40), wherein the electric rotary machine (10) is mechanically supported by resting against the frame (40), and wherein at least one recess (81) is formed in at least one support surface (80), with which one of the two elements, electric rotary machine (10) and frame (40), rests against the other element for mechanical support, in order to space the electric rotary machine (10) and the frame (40) apart from each other in certain areas, the recess (81) forming an empty space. With the drive device and drive unit proposed here, solutions are provided that enable a high efficiency of an electric rotary machine in a simple, cost-effective and space-saving manner.
