PROCESS OF MANUFACTURE OF SLIP-RING ASSEMBLY OF ELECTRIC MACHINE Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: salient feature of invention lies in that ring is formed from blank and moulded in plastic. Blank has technological partitions and tooth-shaped protrusions which are bent simultaneously with formation of protrusions for attachment of leads-out of stator winding prior to tolling of blank. Mentioned protrusions are formed with punching of blank material and with its bending to side opposite to tooth-shaped protrusions to create hooks. Then hooks are drawn to necessary dimensions. Proposed process of manufacture of hooks makes it possible to reduce labour input into fabrication of slip-ring assembly and to provide for automatization of process of coiling of conductors of winding sections of armature and of attachment of their leads. EFFECT: reduced labour input. 7 dwg
