Drive with segmented inverter housing

A drive, comprising:

• a dynamoelectric rotary machine including a shaft;
• an add-on part comprising multiple circuit boards having arranged thereon actuator or inverter components and arranged in a star-shaped manner such that a central one of the circuit boards is surrounded by peripheral ones of the circuit boards, with the peripheral circuit boards being electrically conductively connected to the central circuit board, said central circuit board having a central opening for passage of the shaft, at least one of the peripheral circuit boards being bent at a predetermined angle with respect to the central circuit board on a bending section, and a peripheral cover composed of at least two segments which are made of a material with high thermal conductivity, each of the at least two segments being in direct thermally conductive contact with at least one of the peripheral circuit boards;
• a cooling unit generating a cooling air flow for cooling the add-on part and the dynamoelectric rotary machine,
• wherein the dynamoelectric rotary machine, the add-on part and the cooling unit are arranged axially one behind the other such that the add-on part is arranged axially between the dynamoelectric rotary machine and the cooling unit.
