The device according to the invention offers the advantage that by means of at least two drive positions and a neutral position of a planetary gear as a drive transmission for an electric machine, this electric machine can be used both as a starter for starting the internal combustion engine and as a generator for supplying power to an electrical system of the motor vehicle. The disposition of the electric machine connected in series with the planetary gear, for example in the drivetrain of the motor vehicle between a coupling and a manually shifted transmission preferably on a transmission input shaft, in particular has the advantage that the electric machine can remain in constant engagement without expensive devices for meshing and demeshing a conventional starter, and a control of the planetary gear based on fixed parameters can be carried out simply by means of the motor control.

1. An electric machine for starting an internal combustion engine and for supplying voltage to an electrical system of a motor vehicle, wherein the electric machine is operatively connected to a planetary gear which can be used to couple the electric machine to the internal combustion engine and wherein by means of switching the planetary gear between an internal gear on the one hand, which is locked in relation to a housing of the planetary gear, and the internal gear on the other hand, which is locked in relation to a rotating planetary gear carrier, the electric machine can be switched between a motor operation and a generator operation, characterized in that a mechanical switching means disposed between a fixed housing part and the internal gear (9) can be moved in the circumference direction by means of a drive mechanism and in a first end position (I), locks the internal gear (9), and in a second end position (II), locks the internal gear (9) to the planetary gear carrier (18).
