Carbon Brush Holders

Generator Brush Rockers

Part No. Generator Brush Rockers

Generator brush rockers — the adjustable ring assembly that mounts brush-holder spindles and sets brush position at the correct neutral zone on brushed DC generators and AC generator exciter collector systems. Built for stable, low-spark current collection with alignment marks for precise commutation setting.

Application	Generator brush rigging — the rocker ring carries the brush-holder spindles and allows the brush angular position to be adjusted to the correct commutation/neutral zone, minimizing sparking and keeping stable current collection. Used on brushed DC generat

Compatible Models

Brushed DC generators (commutator-type) — brush rocker set to the neutral zone AC synchronous generator excitation systems — collector (slip) ring brush rigging Brushed alternator / generator sets (e.g. Kohler-style brush-holder assemblies) Industrial motor-generator sets and exciter brush systems (GE / Westinghouse-style machines — verify) **Always verify**: generator make/model ring diameter spindle count

Description

Generator brush rockers are the brush-rigging yokes of generators: the rocker ring holds the brush-holder spindles and can be rotated to adjust the brush angular position, minimizing sparking and maintaining stable current collection. They are used wherever rotor current is fed through stationary brushes — DC generators on the commutator, and AC synchronous generator exciters on collector (slip) rings.Dr. Mithun Mondal's Electrical Engineering AcademyGeneratorStop

Construction

Metal-alloy ring and brush-holder spindles with insulating and connector-ring components
Multiple brush-holder stations around the commutator / slip rings
Rotatable mounting with alignment marks for neutral-zone setting

Setting & Maintenance

Set the rocker at the neutral zone; incorrect positioning causes sparking and burn marks on brush faces and commutator/rings
Align rocker marks with the machine's reference marks after brush replacement
Keep brushes free-moving in their holders with correct spring pressure

Fitment

Brushed DC generators, AC synchronous generator exciter collector systems, brushed generator sets
Industrial motor-generator sets (GE / Westinghouse-style machines)
Fitment is per SKU — confirm generator make/model, ring diameter, spindle count and setting marks before ordering
