SEALED STATOR ASSEMBLY AND ENGINE (VERSIONS) Russian patent published in 2016 - IPC H02K1/18 H02K21/14 H02K7/09 H02K3/42 H02K9/08 

FIELD: engines and pumps.

SUBSTANCE: claimed invention relates to sealed stator assembly to be used in electrically-drive engines such as the compressor drive with electric drive. Said sealed stator assembly comprises the stator including the armature and end zone and ceramic barrel to confine the stator armature surface. The stator end zone adjoins the stator armature and comprises the stator winding outhangs. Note here that the stator end zone accommodates the stator limiting wall. The ceramic barrel and the stator limiting wall confine the space meant for housing the rotor. Note here that said stator inner wall has the inner surface facing the area of stator winging overhang location and outer surface facing the inner surface confined by said stator wall and said ceramic barrel. Note also, at least, a part of said inner surface has the protective ply containing the conducting metal while said stator wall contains the rust-proof metal.

EFFECT: decreased losses for eddy currents.
