Specifications: The carbon brush of the generator is also called the brush, because its material is "carbon", so it is often called "carbon brush". The function of carbon brush is to provide external power (usually DC excitation current) of generator to rotor winding (excitation winding) through slip ring on collector ring. In this way, when the rotor rotates, the incoming DC current will continue to from end of the rotor, thus making the generator rotate in direction. The carbon brush is connected to the power supply to provide power for the rotor. features: Model: 168F/188F The carbon brush is applicable to 168F 2KW-3KW/188F 5KW-8KW gasoline generator Made of high-quality materials, with long service life Carbon brushes are small and easy to install Color: black Product name Applicable mechanical model Distance from mounting hole 2-3KW carbon brush 2/2.8/32kW 2.2cm generator 5-8KW carbon brush 5/6.5/7.5/8KW 2.4cm generator Package includes 1 xCarbon brush holder Made of high quality material, durable and practical to use.
