Product Details

In automotive applications, carbon brushes are predominantly used in starter motors, alternators, and various electric motors, including those for wipers, power windows, and seat adjusters. The performance of these brushes significantly influences the vehicle’s overall performance and lifespan.
Huayu Carbon’s main automotive applications are:
1. Starter Motors: Responsible for starting the engine, the starter motor’s carbon brushes ensure efficient current transmission to the motor windings, allowing the engine to start swiftly and reliably.
2. Alternators: Alternators produce electricity when the engine is running, charging the battery and powering the vehicle’s electrical systems. The carbon brushes in alternators facilitate current transfer, ensuring a stable power supply and optimal functioning of the vehicle’s electrical components.
3. Electric Motors: Electric motors for power windows, windshield wipers, and seat adjusters in vehicles rely on carbon brushes for efficient operation. These brushes maintain a consistent electrical connection, ensuring smooth and reliable operation of these motors.
Huayu Carbon is committed to continuous innovation and improvement in materials and design, striving to enhance the performance and durability of carbon brushes to meet the evolving needs of modern vehicles.
