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.
