Abstract

The invention discloses a material used for preparing a brush for a motor of a dust collector. The brush comprises a matrix powder material and a binder, the matrix powder material comprises graphite,silicon carbide, polytetrafluoroethylene, carbon fiber powder, graphene powder, additives and curing agents, and the ratio of the parts by weight of the matrix powder material to the binder is 5-8:1-2. According to the brush for the motor of the dust collector, prepared by employing the material, the resistivity is low, the wear resistance is good, the spark grade is low, and the product stability is good; and the motor of the brush is high in degree of vacuum so that the usage requirements of high efficiency and high lifetime of the high-efficiency type dust collector motor can be met.

Description

technical field [0001] The invention relates to a material used for electric brushes for vacuum cleaner motors, in particular to a material for preparing electric brushes suitable for high-efficiency vacuum cleaner motors, and belongs to the field of motors. Background technique [0002] The brush is a conductive part used in the motor to contact the commutator or slip ring to form an electrical connection, and is an important component of the motor. As a sliding contact body that imports and exports current, it has good electrical, thermal and lubricating properties, and has a certain mechanical strength and the instinct to suppress commutation sparks. It is widely used in various AC and DC generators, synchronous motors, battery DC motors, crane motor collector rings, various types of welding machines, etc. Almost all DC motors and commutation motors use brushes. [0003] With the development of science and technology, the types of motors and the working conditions of use...
