Technical Field

The utility model relates to the technical field of brush motor protection, in particular to a protection device for preventing carbon brushes of a brush motor from aging.

Background

The motor carbon brush is a generic term for a carbon brush of a motor and a carbon brush of a generator. The carbon brush of the motor is like a rubber strip for wiping a pencil, a lead is led out from the top, the volume is large and small, the motor has the function of changing the current direction, the motor is divided into a direct current motor and an alternating current motor, and the direct current motor is used for changing the conductive coil of a rotor, so that the magnetic pole of the rotor is changed, and the movement of the motor is changed. The carbon brush is used on a commutator or a slip ring of the motor as a sliding contact body for leading out and leading in current, has good electric conduction, heat conduction and lubricating properties, and has certain mechanical strength and the instinct of commutating sparks. Almost all brush motors use carbon brushes, which are an important component of brush motors. The motor has different conditions, so the technical performance is greatly different, and the application occasions are different. Most of the current generators on the market are not provided with carbon brush protection devices, when the generators are operated in severe environments, the carbon brushes are exposed to cause dust and other foreign matters to enter, the carbon brush is easy to be blocked and strike fire, the service life of the generators is shortened, and abrasion dust generated when the carbon brushes are used cannot be removed in time.
