Air-cooled rotating electrical machine for forced ventilation machine, has cooling channels and medium running in stator and in rotor for self and forced ventilation

摘要

The air-cooled rotating electrical machine (1) has cooling channels (8,9) and a medium (6,10) running in a stator (2) and in a rotor (3) for self and forced ventilation. The medium produces a cooling air flow into the partial common cooling channels. A check valve (11) is present in the cooling channels.
