Electric Part Motor Round Carbon Brush 6.3 X 14 MM

Key Information Analysis:

1. Product Type: Round Carbon Brush
   Made by pressing a mixture of high-purity graphite and a small amount of metal powder (such as copper or silver), it has a cylindrical structure and features good electrical conductivity, wear resistance, and adaptability. Through 弧形 contact with the motor commutator, it achieves stable current conduction, driving the motor to operate continuously.
2. Structural Features:
   • Round Design: The cylindrical shape with a diameter of 6.3mm makes it suitable for round brush holders. Its contact with the commutator fits better on the arc surface, reducing the risk of poor contact.
   • Length of 14mm: It belongs to the small-to-medium carbon brush specification and is applicable to low-to-medium power motors (usually 500-1500W).
3. Compatibility Range:
   Based on its round structure and dimensions, it is mainly suitable for brushed motors in the following equipment:
   • Small electric tools: Such as handheld sanders, micro electric drills, portable polishers, etc.
   • Household appliance motors: Drive motors of some models of blowers, small water pumps, and kitchen mixing equipment.
   • Industrial auxiliary motors: Small conveyor belt motors, ventilation equipment motors, etc.
     The core of compatibility is that the diameter of the carbon brush must completely match the circular aperture of the motor's brush holder (with an allowable error of ≤0.1mm), and the length must be consistent with the original carbon brush. Otherwise, it will affect installation stability and current conduction.
4. Functions and Roles:
   • Serves as a "conductive medium" for motors with round brush holders, ensuring efficient current transmission from the stator to the rotor and maintaining the normal operation of the equipment.
   • The round contact surface reduces the friction area with the commutator, making it suitable for motors with medium rotational speeds and lowering operational noise.
5. Replacement Tips:
   Check and replace the carbon brush when the equipment shows the following conditions:
   • The carbon brush is worn down to less than 1/3 of its original length (about 5mm).
   • Obvious sparks appear at the brush holder during motor operation, accompanied by a high-frequency "sizzling" sound.
   • The equipment lacks power after startup or shuts down intermittently.
