Replacement Spare Parts Electric Motor Carbon Brushes 5×8×14.5/16 MM With Great Conductivity

Key Information Analysis:

1. Product Features: High Conductivity Carbon Brushes
   Manufactured using a pressing process that combines graphite with high-purity copper powder (copper content ≥70%), it ensures low resistance and high current conduction efficiency. The special formula allows the carbon brush to maintain stable conductive performance even under high-speed friction, reducing energy loss and making it suitable for precision devices with strict requirements on power output.
2. Compatibility Range:
   Based on its small size of 5×8×14.5/16 mm, it is mainly applicable to micro brushed motors in the following devices:
   • Precision electric tools: Such as micro engraving machines, jewelry polishers, dental tools, etc.;
   • Electronic equipment: Cooling fans of projectors, motors of security monitoring pan-tilts, drive motors of small printers;
   • Models and robots: Drive motors of aircraft/car models, power units of educational robots.
     The core of compatibility lies in the size matching perfectly with the motor's brush holder (with an error ≤0.1mm). Special attention should be paid to distinguishing between the two length specifications of 14.5mm and 16mm to avoid poor contact caused by length deviation.
3. Size Specifications: 5×8×14.5/16 MM
   This size belongs to micro carbon brushes, specially designed for low-power motors (usually ≤500W). The 5mm thickness and 8mm width ensure stable installation in narrow spaces, while the lengths of 14.5mm and 16mm provide sufficient wear allowance (with a service life of approximately 500-1000 hours).
4. Functional Advantages:
   • High Conductivity: The copper-based formula reduces resistance by 30%, minimizing heat generation and improving motor efficiency;
   • Precise Fit: High-precision manufacturing process (tolerance ≤±0.05mm) ensures perfect contact with micro commutators;
   • Self-lubrication: The graphite component reduces the friction coefficient, lowering noise and extending the commutator's service life.
5. Replacement Tips:
   The carbon brush should be replaced in time when the device shows the following conditions:
   • The carbon brush is worn down to less than 1/2 of its original length (about 7-8mm);
   • The motor has a delayed start or obvious speed fluctuations;
   • The device experiences abnormal vibration or there is a burning smell at the carbon brush.
