ELECTRICAL MACHINE IN PARTICULAR SUBMERSIBLE ELECTRIC MOTOR WITH ENCLOSED-TYPE STATOR Russian patent published in 2014 - IPC H02K5/128 H02K9/197 F04D13/08 F04D29/58 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering and may be used in submersible electric motor with enclosed-type stator. Electrical machine has stator frame (4) and winding package (11) surrounding rotor (2) of the electrical machine (1), which is located in stator frame (4) and has axial-directed operating zone (16), which is designed for electrodynamic interaction of winding package (11) with rotor (2); at that stator frame (4) at the side faced to rotor (2) has a circumferential open gap, which in its axial lengths complies with axial length of the winding package (11) operating area (16) and where electrically non-conductive separator pipe (19) of the electric machine (1) is installed and this pipe is sealed in regard to stator frame (4) so that winding package (11) is separated hermetically from rotor (2), at that separator pipe (19) passes in axial direction only in the operating area (16) of winding package (11).

EFFECT: improving durability and efficiency factor.
