STATOR OF HIGH-VOLTAGE ELECTRIC MACHINE Russian patent published in 1994 - IPC

FIELD: electrical engineering; manufacture of high-voltage electric machines. SUBSTANCE: stator of high = voltage electric machine has core of magnetic circuit 1, insulating box 2, detachable cover plates 3 installed on core teeth in area where they get out of slot and directing upper semi-branch of coil being fitted in slot; cover plates are fixed by their projections in recess on insulating box; and also upper semi-branch 4 and lower semi-branch 5 of coil. Provision of bending off of coil lower semi-branches and corresponding recess in extreme sheets of magnetic circuit core in area where it gets out of slot makes it possible to exclude relative touching of corners of slot and end face parts of lower and upper semi-branches of coils. EFFECT: prevention of damage to coil insulation in process of fitting in slots on magnetic circuit core. 4 dwg
