[0002] Brush holder refers to the device for installing brushes. Its main functions include supporting and positioning motor brushes and reducing the wear between motor brushes and rotating parts. In double-fed asynchronous wind turbines, the brush holder applies spring pressure reduction to the carbon brushes in rolling contact with the surface of the collector ring, so that it can stably conduct current between the fixed body and the rotating body. The collector ring is also called a conductive ring, slip ring, collector ring, and collector ring. It is a conductive metal ring that contacts the brush and allows the current to flow from one part of the circuit to another part through sliding contact. The brush holder is quickly stamped and formed by stamping equipment during the production process.
