Description

Special brush of motor for household appliance base

Technical Field

The utility model relates to an electric brush technical field specifically is a special brush of motor for domestic appliance base.

Background

Carbon brushes, also called brushes, are widely used as a sliding contact in many electrical devices. The carbon brush mainly comprises graphite, impregnated graphite and metal (copper and silver) graphite in product application. The carbon brush is a device for transmitting energy or signals between a fixed part and a rotating part of a motor or a generator or other rotating machinery, is generally made of pure carbon and a coagulant, is generally square in shape, is clamped on a metal support, is tightly pressed on a rotating shaft by a spring inside, and transmits electric energy to a coil through a phase changer when the motor rotates. The carbon should be periodically maintained and replaced and cleaned.

Brushes (Brush) are an important component of an electric machine, responsible for conducting electric current between a rotating and a stationary part. Since it is made of graphite, it is also called carbon brush.

The brush is usually mounted on a commutator or slip ring and is a sliding contact. It is required to have the characteristics of smoothness, wear resistance, good conductivity and the like. Depending on the application, they are either partly metallic parts (copper, silver, molybdenum), rich or made entirely of metal.
