Description

This is a Crompton motor carbon brush holder — a box-type, stud-mounted brass brush holder designed for Crompton DC motor and generator commutator positions, and compatible in family with Crompton Parkinson / Crompton Greaves wound-rotor slip-ring machines. A representative commercial specification for this holder family is: suitable brush size 16 × 25 mm, overall length 5.0 inches, brass material, max current 150 A (DC motor application, per Mittal Electrical). The holder provides the brush box, lead slot and terminal interface for the flexible brush lead; the spring and wear device are normally separate items. Because Crompton fitment is machine-specific, verify the brush box (T × W), holder length, stud diameter, spring type and mounting against the original holder before ordering.

Features & benefits:

Crompton DC-motor holder design — box type, stud mounted
Brass body — corrosion-resistant, high-conductivity current path
Reference brush box 16 × 25 mm; 150 A class (per Mittal Electrical holder spec)
Lead slot + terminal interface — accepts flexible brush leads with terminal eyes
Suits Crompton Parkinson / Crompton Greaves DC machines and slip-ring motor repair (verify per machine)
Quality-checked before dispatch; confirm brush box, length and stud with supplier
