STATOR OF ELECTRIC MACHINE Russian patent published in 2007 - IPC H02K1/20 H02K9/22 

FIELD: electric engineering and electro-mechanical industry, in particular, cooling of electric machines with gas cooling with axial cooling of rotor and tangential cooling of stator.

SUBSTANCE: stator of electric machine with gas cooling contains core with tooth zone and yoke zone, with radial ventilation channel, and also cover and longitudinal walls, mounted between core and cover with forming of alternating zones of high and low pressure, in accordance to current invention, core is provided with thermal elements, mounted in tooth zone of ventilation channels with partial protrusion into yoke zone of stator core.

EFFECT: improved cooling of electric machines with small value of air gap by increasing cooling efficiency of tooth zone of electric machine stator core.
