Carbon motor brushes Dedra YSG069 — replacement electrographite brushes for power tools

Replacement electrographite motor brushes Dedra YSG069 are conductive carbon wear parts designed for use in compatible electric motors and power tools. These brushes transfer electrical current between the stationary and rotating components via the commutator, enabling reliable motor operation. They are intended for routine maintenance and repair to restore electrical contact, reduce arcing, and prolong the service life of the motor within devices that accept this brush form and dimensions.

Advantages

Electrographite construction combines good conductivity with reduced wear on the commutator compared with harder carbon variants. The brushes are manufactured to consistent dimensions and material composition to provide stable contact pressure and predictable wear behavior. Their design minimizes electrical noise and arcing under normal load conditions, which helps maintain motor efficiency and reduces the need for frequent replacements when installed correctly.

Suitable for

• Replacement parts for compatible handheld and stationary power tools with brush-type motors
• Maintenance and repair of electric drills, grinders, saws, and similar equipment
• Workshop or field service kits for on-site motor servicing

Key specifications

• Material: electrographite (conductive carbon)
• Function: electrical conduction between stator and rotor via commutator
• Intended use: wear part for brushed DC or universal motors in power tools
• Performance aspects: stable contact pressure, reduced arcing, predictable wear characteristics

How to use

Before installation, disconnect power and follow the tool manufacturer's service instructions. Remove the motor housing or brush caps to access worn brushes. Extract the old brushes, noting spring and holder orientation, and insert the new electrographite brushes in the same position. Ensure proper seating against the commutator and that springs apply consistent pressure. Reassemble the tool, then run the motor at no load for a short period to allow the brushes to seat fully and confirm correct operation without excessive sparking.

Usage recommendations

Inspect commutator condition before fitting new brushes; replace or machine the commutator if heavily grooved or pitted. Use brushes on motors for which the physical size and shape match manufacturer specifications. Replace brush pairs together to maintain balanced performance and check connector and spring contacts for cleanliness and secure fit during regular maintenance intervals.
