Anlaufbürsten

Anlaufbürsten, also known as starter brushes or run-in brushes, are a type of brush used in various mechanical applications, particularly in motors and generators, during their initial operating period. Their primary function is to facilitate a smooth and controlled break-in process for components that experience friction, such as commutators or slip rings. Unlike brushes designed for continuous operation, Anlaufbürsten are typically made from softer materials or have a modified surface texture. This allows them to gradually wear down the microscopic irregularities present on the mating surfaces of the rotating parts.

The use of Anlaufbürsten helps to reduce initial wear, minimize electrical arcing, and improve the overall efficiency and longevity of the equipment. By carefully shaping the contact surfaces during the run-in phase, they promote better electrical conductivity and a more uniform wear pattern. Once the break-in period is complete, these specialized brushes are usually replaced with the standard operating brushes. The duration and method of using Anlaufbürsten are often specified by the equipment manufacturer to ensure optimal results. This practice is crucial for high-performance or precision machinery where initial surface finishing is critical for long-term reliability.
