We would like to introduce our "Super Micro Brush." For small motors with an outer diameter of 10 mm or less, there is no space to accommodate traditional carbon brushes, so we use metal brushes clad with a thin plate spring. This product is designed to break the conventional concepts of brush shapes and holding methods, achieving ultra-miniaturization to be compatible with 10 mm motors. 【Features】 ■ Five times longer lifespan compared to metal brushes ■ 10% noise reduction compared to metal brushes *For more details, please refer to the PDF document or feel free to contact us.

Our "carbon brushes" are manufactured using a method called "powder metallurgy." Powder metallurgy is a process that uses several types of metal powders as raw materials, which are mixed in appropriate proportions, placed into a mold, shaped under high pressure, and then heated in a furnace at a temperature below the melting point of the metal to produce materials or metal products. In a broader sense, it also includes cases where non-metal powders such as carbon and oxides are used as raw materials.
