Abstract

A selector drive for automatic manual transmissions has an electric motor, the rotational motion of which can be transmitted to the selector mechanism for the selection of a selector position by way of a mechanical transmission chain. An electric motor (1) of the mechanical transmission chain is an electric motor with defined step width, whereby the required step number for the selection of the selector position in the selector mechanism can be determined through fixed geometrical conditions or distances according to the stipulations of the individual step angle of the electric motor and the distance between the selector positions.
