Description

Overview

Carbon brush holder (brush box) — the mechanical assembly that holds the carbon brush against the commutator or slip ring: the brush sits in the box and a spring applies constant pressure for stable, low-spark current transfer.淄博广联电机厂

Construction

Brass / bronze brush box (corrosion-resistant, conductive, good heat transfer)
Insulated carriers and studs (DMC/phenolic or insulated rods) for brush-circuit isolation
Spring on brush center — prevents uneven wear; pressure direction and position matter
