Motor Brush Replacement: 1 Pair of 6.5×11×32mm Carbon Brushes for Vacuum Cleaners (Electric Spare Parts)

1. Product Identification

• Type: Replacement carbon brushes (a pair, designed for simultaneous replacement).

• Dimensions: 6.5mm (thickness) × 11mm (width) × 32mm (length) — precise sizing ensures compatibility with specific vacuum cleaner motors.

• Application: Spare parts for vacuum cleaner motors, classified as essential electric components.

2. Core Function

• Electrical Conduction: Transmits current from the vacuum cleaner’s power source to the motor’s rotating rotor via contact with the commutator, enabling the motor to drive the suction mechanism.

• Wear Protection: Designed to wear gradually during operation, safeguarding the motor’s commutator (a more expensive component) from excessive damage.

3. Compatibility

• Specifically tailored for vacuum cleaner motors requiring carbon brushes of 6.5×11×32mm dimensions.

• Suitable for both household and commercial vacuum cleaners with brushed motors (verify your vacuum’s model or motor specifications for size matching).

4. Key Features

• Material: Typically a graphite-based composite (may include small amounts of copper for improved conductivity) to balance electrical performance and wear resistance.

• Pair Design: Sold as a pair to ensure even wear on the commutator, preventing uneven pressure that could damage the motor.

• Standardized Fit: Dimensions 6.5×11×32mm ensure a snug fit in compatible brush holders, maintaining stable contact during high-speed motor operation.

5. Replacement Indicators

• When the brush length is worn down to less than half of the original (e.g., from 32mm to <16mm).

• Excessive sparking from the vacuum cleaner’s motor during operation (signals poor contact due to wear).

• Reduced suction power, intermittent operation, or unusual motor noise (common signs of degraded brushes).

6. Installation Notes

• Replace both brushes in the pair simultaneously to ensure balanced pressure on the commutator.

• Clean the commutator surface with isopropyl alcohol before installation to remove carbon dust buildup.

• Ensure the brushes fit securely in the holder without binding, as loose contact can cause overheating or motor inefficiency.

7. Importance in Vacuum Cleaners

• Enables reliable power transfer to the motor, directly impacting suction performance.

• Protects the motor’s commutator and rotor from damage, extending the vacuum cleaner’s lifespan.

• Ensures consistent operation, preventing sudden breakdowns during cleaning tasks.
