Abstract: A stator segment of a stator of a generator for a wind turbine has at least one stator laminated core which has at least two stator lamination stacks, wherein adjacent stator lamination stacks of the at least two stator lamination stacks are in each case spaced parallel to one another in an axial direction and forming in each case one stator cooling duct with a stator cooling duct width through which a cooling medium can be guided, in particular in a radial direction. A rotor segment of a rotor for a wind turbine has two or a plurality of magnet units are disposed spaced apart from one another in an axial direction, wherein the magnet units disposed adjacently in the axial direction define a circumferential gap with a gap width for feeding and distributing a cooling medium.

Abstract: A generator, in particular a generator for a wind power installation, the generator having: an air supply duct and a separate exhaust air chamber, in particular two or a plurality of exhaust air chambers, which are fluidically connected to the upstream air supply duct, a stator segment having a stator active unit and a rotor segment which is disposed so as to be rotatable relative to the stator segment about a rotation axis and has a rotor active unit, the rotor active unit and the stator active unit being disposed so as to be mutually spaced apart by an air gap by way of which the exhaust air chamber is fluidically connected to the upstream air supply duct, wherein an air-conveying device is disposed downstream of the exhaust air chamber that is configured for cooling the rotor active unit and the stator active unit, the air-conveying device for cooling the rotor active unit and the stator active unit supplying cooling air to the air gap by way of the air supply duct, and discharging from the air gap cooling air heated by the rotor active unit and the stator active unit by way of the exhaust air chamber, the exhaust air chamber being configured for discharging the heated cooling air in a radial direction in terms of the rotation axis.
