CLOSED ELECTRICAL MACHINE Russian patent published in 2019 - IPC H02K9/26 H02K9/02 

FIELD: electrical engineering.

SUBSTANCE: closed electric machine, shaft of which has axial cavity filled with desiccant, and radial holes at ends, by means of which cavity is interconnected with internal cavity of machine. Hollow elements in the form of pipes are inserted into radial holes on one side of the shaft, the axial cavity of the shaft is interconnected with the cavity of pipes. Pipes are inserted into radial holes at depth of wall thickness of hollow part of shaft, length of pipes exceeds thickness of wall of hollow part of shaft.

EFFECT: creation of forced air circulation from cavity of closed electrical machine through container with desiccant and increase of moisture absorption efficiency.
