Carbon motor brushes Dedra YSG040 – replacement electrografite brushes for power tools

Electrografite carbon motor brushes Dedra YSG040 are replacement contact elements designed for commutator-type electric motors used in power tools. These carbon brushes serve as conductive interfaces between the stationary wiring and the rotating commutator segments, enabling consistent current transfer. They are intended for routine maintenance and part replacement to restore motor performance, reduce sparking at the commutator, and maintain stable operation in handheld and stationary equipment.

Advantages

Electrografite composition provides a balance of good electrical conductivity and controlled wear, which helps extend commutator life and maintain reliable electrical contact. The brushes are manufactured to match typical dimensions and mechanical features of compatible motor holders, ensuring straightforward installation and secure seating. Using appropriate replacement brushes reduces motor noise and sparking, contributes to smoother starting and running characteristics, and supports predictable maintenance intervals.

Suitable for

• Routine maintenance and replacement in commutator motors of handheld power tools
• Repair and refurbishment of small stationary electric machines with brush-type motors
• Reducing sparking and improving contact stability in motors subject to wear
• Workshops and service centers performing scheduled motor overhauls

Key specifications

• Material: electrografite (carbon) formulated for electrical contact and wear characteristics
• Function: conductive brush for commutator-type DC or universal motors
• Typical application: power tools and small electric machines requiring brush replacements
• Design features: form and mounting adapted for replaceable brush holders in consumer and professional tools
• Performance attributes: stable current transfer, controlled brush wear, reduced sparking

How to use

Switch off and disconnect the tool from the power supply before starting any work. Access the motor brush holder by removing the appropriate cover or housing screws according to the tool manufacturer's service instructions. Remove the worn brush assembly, noting the orientation and any spring or connector positions. Insert the replacement electrografite brush into the holder with correct polarity and seating, connect any terminal leads or springs, and reassemble the housing. After replacement, run the motor briefly under no-load conditions to check for proper seating, minimal sparking, and normal sound. If excessive sparking or unusual noise persists, recheck installation or consult a qualified technician.

Usage recommendations

Use carbon brushes of matching size and shape for your specific motor model. Perform inspections at regular intervals based on operating hours and load conditions, and replace brushes before they become too short to ensure safe and reliable motor operation. Avoid operating the tool in heavily contaminated environments without appropriate maintenance, and follow the tool manufacturer's safety and service guidelines when replacing components.
