Description

Slip ring brush holder AC series is dedicated brush holder assemblies for AC slip ring applications including wound rotor induction motors and synchronous alternators. The housing is made of high-performance reinforced phenolic resin, offering outstanding insulation, heat resistance and mechanical strength to withstand harsh industrial operating environments. Equipped with stainless steel constant force springs, the AC series brush holder keeps uniform pressure on carbon brushes during continuous rotation, minimizing electrical sparking, lowering slip ring wear and extending service life of both carbon brushes and slip rings. Copper or silver-plated copper terminals ensure stable electrical conductivity and reduce heat buildup under AC excitation load. This series supports single-leg and double-leg mounting configurations to fit different installation requirements. Multiple standard brush slot dimensions are available to match most common AC slip ring carbon brushes. It is a reliable OEM replacement spare part for power plants, mining equipment, cement factories and other heavy industrial AC rotating machinery repair.
