ELECTRICAL MACHINE ARMATURE Russian patent published in 1996 - IPC

FIELD: electrical engineering; automotive industry. SUBSTANCE: correcting material is made in the form of set of balancing rods; magnetic-circuit stack built up of laminations has axial cylindrical ducts. Duct walls are provided with crosswise notches for holding balancing rods placed in duct. Number of balancing rods per set depends on degree of unbalance and length of greatest of them does exceed duct depth. EFFECT: reduced cost, improved mass and size characteristics, improved reliability of armature due to new design of stack components and due to their use as auxiliary parts for mounting balancing rods firmly held in magnetic-circuit ducts and by centrifugal forces. 5 dwg
