Abstract: FIELD: electrical and electromechanical engineering; water- or oil-cooled electrical machines. SUBSTANCE: heat releasing stator components (armature winding) and heat-transfer ones ( cooling winding) are placed in stator core slots over inner and outer diameters of core, respectively. Cooling winding tubes are disposed in slots in two layers and joined into parallel circuits so that coolants flow through circuits in opposition over stator circumference. Such connection eliminates impact of coolant heating as it flows through cooling winding. Proposed relative arrangement of these windings ensures adequate heat transfer from armature winding. At the same time internal voltage is not induced in cooling winding tubes as they are disposed beyond main magnetic flux area. EFFECT: enhanced stator manufacturability, operating efficiency, and reliability if its cooling system. 8 cl, 4 dwg
