Replacement Electric Spare Parts: 6×10×16mm Carbon Brush

1. Product Identification

• Type: Replacement carbon brush (a consumable spare part for electric devices).

• Dimensions: 6mm (thickness) × 10mm (width) × 16mm (length) — precise sizing ensures compatibility with specific motor models.

• Category: Electric spare parts, primarily used in motors of power tools, appliances, or industrial equipment.

2. Core Function

• Current Conduction: Transmits electrical current between the stationary and rotating parts of a motor (e.g., from the power source to the rotor via contact with the commutator or slip ring).

• Wear Buffer: Designed to wear gradually during operation, protecting more expensive motor components (like the commutator) from excessive damage.

3. Compatibility

• Suitable for electric motors in devices that require carbon brushes of this exact size (6×10×16mm). Common applications include:

• Small power tools (e.g., drills, sanders, grinders).

• Household appliances (e.g., vacuum cleaners, mixers with brushed motors).

• Industrial machinery with low-to-medium power motors.

• Note: Always check your device’s user manual or motor specifications to confirm size compatibility.

4. Material & Performance

• Typically made of graphite-copper composite (5–15% copper content) to balance:

• Electrical conductivity: Efficiently transfers current.

• Wear resistance: Withstands friction from contact with rotating commutators.

• Service life: Approximately 40–80 hours of standard use (varies by motor speed, load, and operating conditions).

5. Replacement Indicators

• When the remaining length of the carbon brush is less than half of the original (≈8mm for this 16mm model).

• Excessive sparking from the motor during operation (signals poor contact or wear).

• Reduced device power, intermittent operation, or unusual motor noise.

6. Installation Tips

• Replace in pairs (if the motor uses two brushes) to ensure even pressure on the commutator, preventing uneven wear.

• Clean the commutator surface with isopropyl alcohol before installing new brushes to remove carbon dust buildup.

• Ensure the brush fits snugly in the holder without binding; loose fits can cause arcing and damage.

7. Key Consideration

• Using a carbon brush with incorrect dimensions can lead to motor malfunction, commutator damage, or electrical shorts. Always verify the required size (6×10×16mm) with your device’s specifications before purchasing.
