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

摘要

The rotary electrical machine comprises a rotor (2), a stator (3) and a cooling device (7), which has multiple radially extending cooling channels (9) formed in the stator. The cooling channels are connected in a communicating manner to an annular gap (6), which is radially formed between the rotor and the stator. The cooling device has a cooling gas introducing device (11) and an inlet section (12) with an inlet port (14) that is tangentially arranged within the annular gap. A deflection section (13) connects the inlet section to one of the cooling channels.
