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.
