Description

In the automotive window regulation system, the window regulator motor is the key device enabling smooth window lifting and lowering. As a core internal component of the motor, the performance of carbon brushes directly determines the stability and efficiency of both the motor and the entire window regulation function. Our company has meticulously developed and produced 3.5×5.5×5 carbon brushes, custom – tailored for window regulator motors. With outstanding quality, they safeguard the window regulation system.

Precise Specifications for Exclusive Compatibility

The dimensions of this carbon brush are precisely controlled at 3.5×5.5×5 (unit: mm), a result of extensive adaptation tests and R & D optimizations. The internal space of a window regulator motor is compact, demanding strict dimensional accuracy for components. The 3.5×5.5×5 specification can be flawlessly embedded in the commutator area of the motor rotor, achieving a high – precision match with the motor’s internal structure. This ensures smooth operation after motor assembly, providing a stable power foundation for window lifting. Whether for the window regulator motors of common family cars or commercial vehicles, this – sized carbon brush offers precise compatibility, combining universality and adaptability.

Premium Materials for Exceptional Performance

– Strict Material Selection: The carbon brushes are made from high – quality carbon graphite materials, which undergo rigorous screening and proportioning. Carbon graphite boasts excellent electrical conductivity, lubricity, and wear resistance, making it an ideal choice for motor carbon brushes. The carbon graphite raw materials we select have high purity and extremely low impurity content. This ensures performance for carbon brushes from the source, enabling stable current transmission during the motor’s high – speed operation, reducing power loss, and enhancing motor efficiency.

– Balancing Conductivity and Wear Resistance: Superior electrical conductivity ensures stable motor current transmission. During frequent window lifting operations, current can be continuously and smoothly transmitted to the rotor via the carbon brushes, allowing the motor to output stable power. This avoids issues like window jamming or weakness caused by poor current transmission. Meanwhile, excellent wear resistance grants the carbon brushes a long service life. When facing continuous friction between the carbon brush and the commutator during motor operation, the 3.5×5.5×5 carbon brush wears slowly. This effectively reduces replacement frequency, cuts after – sales maintenance costs, and ensures the long – term stable operation of the window regulation system.

Exquisite Craftsmanship for Reliable Quality

– Molding Process: An advanced compression molding process is employed. The formulated carbon graphite raw materials are pressed in high – precision molds. Strict control over molding pressure and temperature guarantees uniform density and stable structure of the carbon brushes. The molded carbon brushes have a regular shape, minimal dimensional tolerance, and a smooth surface. They can achieve excellent contact with the commutator, further boosting current transmission efficiency and the smooth operation of the motor.

– Post – Processing: Through meticulous post – processing procedures such as chamfering and grinding, burrs on the carbon brush edges are removed, optimizing both the appearance and performance of the carbon brushes. Chamfering makes it easier to install the carbon brush inside the motor and reduces edge friction damage when in contact with the commutator, extending the service life of both. The grinding process makes the carbon brush surface smoother, reducing contact resistance and facilitating efficient motor operation.

Notable Advantages in Adapting to Window Regulator Motors

– Stable Window Lifting: When the window regulator motor operates, the 3.5×5.5×5 carbon brush can continuously and stably supply current to the motor. This makes the motor rotor rotate at a constant speed, driving the car window glass to lift and lower smoothly. Whether slowly raising to close the window or quickly lowering for ventilation, it operates smoothly without jolts. This enhances the user experience for drivers and passengers and showcases the exquisite texture and high – end performance of the car interior.

– Coping with Complex Working Conditions: The operating environment of a car is complex and variable, and the window regulator motor may face challenges such as high temperatures, humidity, and vibrations. Our carbon brushes, with high – quality materials and exquisite craftsmanship, exhibit good environmental adaptability. In high – temperature environments, the physical and chemical properties of the carbon brushes remain stable, without softening or deformation due to excessive heat. In humid environments, they have strong corrosion resistance, effectively resisting water vapor erosion and ensuring the normal operation of the motor. Thus, the window regulation function remains reliable and durable under various road and climate conditions.

– Extending Motor Service Life: As a wear – and – tear part of the motor, the quality of carbon brushes significantly impacts the motor’s overall service life. The high wear resistance and stable electrical conductivity of 3.5×5.5×5 carbon brushes can reduce wear on the motor’s internal commutator, lowering the maintenance probability of the motor due to carbon brush failures. From the perspective of the motor’s core components, they extend the service life of the window regulator motor, enhancing the durability and reliability of the entire vehicle.

The 3.5×5.5×5 carbon brushes produced by our company, with precise specification compatibility, high – quality material performance, and exquisite manufacturing craftsmanship, are ideal partners for window regulator motors. Whether automotive manufacturing enterprises are seeking stable component matching or the after – sales maintenance market is replacing high – quality carbon brushes, this product can meet demands with outstanding performance. It injects lasting, stable, and efficient power into the automotive window regulation system, helping to create a better car – riding experience and promoting the high – quality development of the automotive parts industry.
