Exhaust gas turbocharger comprising adjusting device

An exhaust gas turbocharger, comprising:

• a variable turbine geometry;
• and
• an adjusting device for actuating the variable turbine geometry, the adjusting device including:
• a housing including a first housing part and a second housing part that abut one another along a dividing plane, the first housing part including a motor mounting and a cooling channel, the cooling channel surrounding the motor mounting in a circumferential direction over at least 180 degrees, the first housing part further including an inlet connection for supplying a coolant and an outlet connection for discharging the coolant;
• an electric motor for rotationally driving an actuator, the actuator arranged on the second housing part, the electric motor including a stator and a rotor, the rotor including a rotor shaft rotatable about an axis of rotation, the electric motor arranged axially with respect to the axis of rotation within the motor mounting such that the axis of rotation extends perpendicular to the dividing plane and the rotor shaft protrudes into the second housing part;
• and
• the second housing part including an electrical connection configured to supply electricity to and control the electric motor;
• wherein the first housing part and the second housing part are fastenable to one another via a plurality of first fastening elements disposed on the first housing part and a plurality of second fastening elements provided complementary thereto and disposed on the second housing part;
• wherein a distance between the plurality of first fastening elements and the axis of rotation is the same as a distance between the plurality of second fastening elements and the axis of rotation;
• and
• wherein the plurality of first fastening elements and the plurality of second fastening elements are arranged evenly distributed in the circumferential direction such that the first housing part and the second housing part are fastenable to one another in a plurality of different rotational positions relative to the axis of rotation;
• wherein the actuator of the adjusting device is mechanically connected to a second actuator of the variable turbine geometry.
