FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in all types of closed electrical machines operating in environments with high relative humidity and dust. On the shaft of the asynchronous electric machine there are hollow elements in the form of pipes filled with a desiccant. Said hollow elements in the form of pipes are inserted into a hollow ring enclosing the shaft. This hollow ring has air inlets and is filled with a desiccant.
EFFECT: improving the manufacturability of the design.
