STATOR OF A C ELECTRIC MACHINE Russian patent published in 1994 - IPC

FIELD: electric machine engineering. SUBSTANCE: stator of A C electric machine has pressure elements with pressure pins enveloping configuration of face stacks of stator core in tooth zone. On side of air gap have protrusions located in air gap. Protrusions have holes for passing of threaded ends of studs. Nuts clamping core axially and preventing tooth zone from pressing out are put on threaded ends of studs. Positioning under nuts of other restoring members reducing thermal stresses in studs is also possible. Studs may be manufactured with central hydraulic channel intended for circulation of liquid cooling agent. EFFECT: reduced labour input and enhanced operational conditions. 4 cl, 6 dwg
