1. A structural concept of a drive for an actuator in a drive train of a motor vehicle, the structural concept comprising:
an electric motor with a motor housing shell and a rotor shaft;
a circuit carrier with a controller for controlling said electric motor;
a gearbox having an output shaft and a gearbox housing shell, said rotor shaft of said electric motor being disposed axially with respect to said output shaft of said gearbox, and said rotor shaft of said electric motor being accommodated in said output shaft in a rotatably mounted manner in a region of said gearbox housing shell;
said circuit carrier disposed between said electric motor and said output shaft of said gearbox, said circuit carrier having a cutout formed therein and said rotor shaft leading through said cutout in said circuit carrier; and
said circuit carrier being equipped with electronic components on both sides, said electronic components including:
a first sensor for detecting a rotor position, said first sensor being disposed outside said cutout on a side of said circuit carrier facing said electric motor, and
a second sensor for detecting an angle of said output shaft, said second sensor being disposed outside said cutout on a side of said circuit carrier facing said output shaft.
