ELECTRICAL MACHINE STATOR Russian patent published in 2014 - IPC H02K1/20 H02K3/24 H02K9/22 

FIELD: electricity.

SUBSTANCE: device includes case (1) with sealed cavity inside, filled with circulating cooling agent fed through reducers, where magnetic conductor (2) and windings (3) are installed. Cavity is formed by internal surfaces of section heads of front winding parts (3), where flow conditioner (4) in the form of closed solid torus ring with cross-section possibly copying the form of cross-section in this plane, is installed. Cooling agent is circulating in cavities formed inside the stator case during operation of electric machine. Cooling agent flow conditioner (4) filling the space inside section heads of front winding parts directs cooling agent flow alongside surfaces, improving cooling conditions.

EFFECT: increased cooling agent flow speed alongside surfaces of sections of front stator winding parts, resulting in better heat exchange conditions and higher operation reliability for stator elements and electrical machine in general.
