INGCO S-AG-CBR-AG6801, Angle Grinder-Carbon Brush-no.56(S-AG-CBR-AG6801)
product details:
Carbon brushes, also known as motor brushes, are essential components within an angle grinder’s motor. Here’s a comprehensive breakdown of their features and function:
General Function:
- Carbon brushes act as conductors, transferring electrical current from the stationary motor housing to the rotating commutator (a cylindrical component within the motor). This current flow powers the motor and ultimately the grinding wheel.
Specific Features:
-
Size and Shape:
- Crucial for proper fit within the brush holder and contact with the commutator of your specific angle grinder model. This designation can be a number (e.g., No. 56) or a size code. Using an incorrect size brush can lead to:
- Reduced grinding power and sparking due to poor contact with the commutator.
- Improper fit in the brush holder, potentially causing a loose brush and damage to the brush, holder, or commutator.
- Crucial for proper fit within the brush holder and contact with the commutator of your specific angle grinder model. This designation can be a number (e.g., No. 56) or a size code. Using an incorrect size brush can lead to:
-
Material Composition:
- Brush: Typically a composite material to balance:
- Conductivity: Efficient current transfer (often uses graphite as the primary conductor).
- Friction: Maintaining contact with the commutator while minimizing wear (may include metal powders).
- Durability: Lasting a reasonable time before needing replacement (resins and binders hold the composite material together).
- Brush Holder: Usually made from a heat-resistant material like:
- Plastic: A cost-effective option for many grinders.
- Ceramic: Provides better heat resistance for high-performance grinders.
- Brush: Typically a composite material to balance:
-
Spring-Loaded Mechanism:
- A spring within the brush holder applies constant pressure between the carbon brush and the commutator as it rotates. This ensures good electrical contact and optimal motor performance.
-
Wear and Replacement:
- Friction between the brush and the commutator causes the brush to wear down over time.
- Some brushes have a wear indicator marking that signifies replacement time.
