A motor system includes: a stator; a rotor; a motor shaft, which is mechanically coupled for conjoint rotation with the rotor, and which defines a radial direction and an axial direction of the motor system; heat-generating components, in particular power semiconductors; a control device which is designed to control an operation of the motor system; and a housing. The housing has a first central chamber, wherein the stator, the rotor and the heat-generating components are arranged inside the first chamber, and wherein the heat-generating components are connected to an outer wall of the first chamber, and has a number of second chambers, wherein the second chambers radially surround the first chamber, and wherein the second chambers form closed channels for guiding cooling air.
