Product Description

Introduction

Molybdenum Disulfide For Carbon Brush is added to the wiper body in the form of powder, which can be used for high-power generators and starter generators. The actual service life is 600 hours. Molybdenum Disulfide For Wiper is also successfully used in the main generator of helicopters with a service life of more than 500 hours.

Molybdenum disulfide plays a key role in enhancing the carbon brushes of motors. As a core additive, it is integrated into the carbon brush material. With its unique layered structure and self-lubricating properties, it forms an efficient lubricating transfer film between the brush and the commutator/collector ring. This not only significantly reduces the coefficient of friction, but also effectively suppresses electric sparks and reduces contact surface wear, enabling the carbon brush to maintain a more stable contact resistance and electrical conductivity during high-speed operation. It is particularly suitable for harsh working conditions such as offshore wind turbines that require high reliability and long-term maintenance-free operation, greatly extending the service life of key components.

With nearly 20 years of research and development experience, we can provide an annual output of 1000 tons of Molybdenum Disulfide For Carbon Brush as a technology product.
