Rotary electrical machine, particularly electric motor or generator, particularly power plant, comprises rotor, stator and cooling device, which has multiple cooling channels formed in stator

摘要

The rotary electrical machine comprises a rotor (2), a stator (3) and a cooling device (5), which has multiple cooling channels (6) formed in the stator. An isolator (11) is arranged in an annular space (7), where a radial inner area (12) is fluidic connected to an area, radially lying outside. A cooling gas flows from the cooling channel in the outer area. The gas flows out in the cooling channel or in an adjacent cooling channel.
