Abstract

The invention discloses a brush for a motor of a treadmill. The brush is prepared by the following method: uniformly mixing a matrix powder material and a binder to prepare a brush raw material mixture, wherein the matrix powder material comprises graphite, flexible graphite powder, talcum powder, graphene, additives and curing agents; performing drying, fragmentation, screening and mixing on thebrush raw material mixture to prepare brush raw material mixture powder; adding the brush raw material mixture powder to a compacting mold for compacting processing to obtain a brush raw billet; performing thermo-curing processing on the brush billet to prepare a brush processed billet; and performing finished product processing on the brush processed billet to obtain a brush finished product. According to the brush, the resistivity is moderate, the wear resistance is good, the commutation performance is good, and the spark grade is low; and more importantly, the noise is low, and the productstability is good.

Description

technical field [0001] The invention relates to an electric brush for a treadmill motor, in particular to a low-noise electric brush for a treadmill motor, which 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, and is one of the important components 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. Almost all DC motors, as well as commutated motors, use brushes. [0003] With the development of science and technology, the types of motors and the working conditions of use are becoming more and more diverse, so various types of brushes are required to meet the various requirements of the motor, so the types of brushes also follow the motor industry. development and more and more. [0004] At present, the m...
