Abstract
A drive unit includes two coaxially aligned electric machines. Each electric machine includes a rotor and stator. Each stator has a stator core lamination packet on which stator coils are arranged. The ends of the stators form end-face coil ends. One coil end forms a switching side for connecting electric current and the other coil end forms a counter-switching side. A housing that accommodates the electric machines is provided. The first of the electric machines with its counter-switching side and the second of the electric machines with its counter-switching side are arranged in the shared housing in such manner that the counter-switching sides face toward one another in the axial direction.
