Abstract:
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).
