What is the role of the electric brush
The hammer brush is mainly to the rotor power supply, can be seen as a wire to understand. Without it, the rotor can not work, do not hammer.
The brush is used as a sliding contact on the commutator or slip ring as an introduction to the current. Its electrical conductivity, thermal conductivity and lubrication are good, and have a certain mechanical strength and reversing spark instinct. Almost all DC motors and reversing motors use brush, which is an important component of the motor
An electric brush is a conductive component that forms a electrical connection with a moving member by sliding contact.
