METHOD OF IMPREGNATION OF ELECTROMECHANICAL CONVERTER STATOR WINDING Russian patent published in 2008 - IPC H02K15/12 H02K15/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and processes of motor building and may be used in production of electromechanical converters, in particular, in sealed version. According to this invention, the impregnation of the stator winding of the said converter includes application of impregnating material onto the stator, drying and solidification of the above material plus filling the gaps between the dummy rotor arranged inside the stator and the stator with winding laid in the stator grooves, while in drying and solidification of impregnator, the dummy rotor is rotated and removed after a complete solidification of impregnator that makes a rolling bearing arranged on the stator inner and/or side surface.

EFFECT: higher efficiency of impregnation thanks to an efficient use of impregnator and ruling out the need in removing the excess impregnator used in formation of the rolling bearing by means of dummy rotor.
