Replacement Spare Parts Electric Motor Carbon Brushes 5×8×14.5/16 MM With Great Conductivity
This is a high-conductivity replacement spare part for electric motor carbon brushes, with dimensions of 5×8×14.5 mm or 5×8×16 mm (length × width × height). Specifically designed for brushed motors in small electric devices, it boasts excellent conductive performance and serves as a key vulnerable component ensuring efficient motor operation.
Key Information Analysis:
-
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. -
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.

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). -
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.
-
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.
In summary, this is a high-conductivity replacement carbon brush for electric motors with dimensions of 5×8×14.5/16 mm. Specifically designed for small precision devices, it ensures efficient and stable operation of micro motors through its excellent conductive performance and precision manufacturing process.
