10080308 Hot Sale Drum Automatic Washing Machine Carbon Brush 5×12.5×37 mm

Key Information Analysis:

1. Product Attribute: Model 10080308 Hot-Selling Carbon Brush for Drum Automatic Washing Machine Motors
   Made by pressing a mixture of high-purity graphite and an appropriate amount of metal powder (copper-silver alloy, with copper content approximately 20%-30%), and subjected to moisture-proof treatment, it has three core characteristics:
   • Household appliance-grade durability: The material balances conductivity and wear resistance, adapting to high-frequency start-stop of washing machines (such as switching between washing and dehydration modes) and humid environments (operating humidity up to 80% or more), with a service life of about 2500-4000 hours (equivalent to approximately 500-800 washing cycles);
   • Precise adaptability: The 5×12.5mm cross-sectional size is specially designed for brush holders of drive motors in drum washing machines. The extra-long 37mm length provides sufficient wear allowance, adapting to drive motors of mid-to-high-end drum washing machines from most mainstream brands (such as Haier, Siemens, Midea, etc.);
   • Priority on stability: The high-purity graphite with few impurities can reduce sparks during current transmission, lower motor operating noise, and avoid excessive noise or vibration of the washing machine caused by carbon brush issues.
2. Compatibility Range:
   Based on the 5×12.5×37mm specification and model 10080308, it is mainly compatible with drum automatic washing machines, especially:
   • Drive motors of household drum washing machines with a capacity of 5-12kg;
   • Inverter or non-inverter drum washing machine motors of some brands (usually with a power of 200-500W).
     The core of compatibility lies in the dual matching of model and size – it is necessary to confirm that the original carbon brush model of the washing machine motor is 10080308, and the 5×12.5mm cross-section fits perfectly with the brush holder (with an error of ≤0.2mm). The 37mm length must correspond to the motor installation space to avoid installation difficulties caused by dimensional deviation.
3. Size Specifications: 5×12.5×37mm
   This size belongs to medium-long carbon brushes dedicated to household appliances. The 5mm thickness fits the compact brush holder structure of washing machine motors, the 12.5mm width provides a stable current conduction area, and the extra-long 37mm length is its prominent feature – it reserves sufficient wear space for long-term use without causing jamming during operation due to being too long. The dimensional accuracy is controlled within ±0.1mm to ensure uniform contact with the commutator and reduce motor noise during the operation of the washing machine.
4. Functions and Roles:
   • As the "current conduction hub" of the washing machine's drive motor, it transmits external current to the rotor through sliding contact with the commutator, driving the drum to complete core actions such as washing and dehydration, ensuring the normal operation of the washing machine;
   • The moisture-proof material design can resist water vapor erosion inside the washing machine, reducing the decline in conductivity or structural damage of the carbon brush due to moisture, and extending the service life of the motor.
5. Replacement Tips:
   The carbon brush should be replaced in time when the drum washing machine shows the following conditions:
   • The carbon brush is worn down to less than 1/3 of its original length (about 12.3mm), or has chips or cracks;
   • The noise at the motor part increases significantly during the operation of the washing machine (such as abnormal "buzzing"), or the rotation speed decreases and vibration intensifies during dehydration;
   • The washing machine frequently has start-up failures (such as the drum not rotating after the program starts), or displays motor-related fault codes (such as E21, E30, etc., which are subject to the brand-specific codes of the washing machine).
