Drive with combined choke

A drive, comprising:

• a housing;
• a dynamo-electric rotary machine arranged in the housing, said dynamo-electric rotary machine comprising a stator, a winding system arranged in the stator, and a rotor which is separated from the stator by an air gap, with the stator and the rotor being located in a motor interior;
• a B-side pot-shaped bearing shield comprising a bearing supporting the rotor for rotation about an axis;
• a converter comprising at least one component selected from the group consisting of power semiconductor, capacitor, control and regulating unit, and communications unit, said converter being situated in a converter installation space which is radially surrounded at least in one section by the B-side bearing shield, wherein the at least one component of the converter is thermally conductively connected to the B-side bearing shield, said converter being arranged, as viewed axially, between the dynamo-electric rotary machine and the bearing of the B-side bearing shield;
• and
• a choke body separating the motor interior and the converter installation space and comprising chokes.
