Abstract

The present invention discloses a manufacturing method of an electric brush for a treadmill motor and an electronic brush manufactured using the method. The materials of the electric brush for the motor belong to the field of material science. The manufacturing method of the electric brush comprises: firstly, uniformly mixing graphite, carbon black, an additive, an adhesive and a firming agent under a condition of heating, then smashing and placing the mixture in a mold, and shaping the mixture via pressing; and secondly, conducting curing treatment, cutting, grinding, punching and line adding. The electric brush for the treadmill motor manufactured using the method is low in noise caused during operation, low in resistance, good in direction switching performance, powerful in interference resistance and long in service life. most importantly, the electric brush is high in abrasion resistance, low in noise and spark grade, sparkless in empty load, and good in product stability.

Description

technical field

[0001] The invention relates to a brush for a motor, in particular to a brush for a treadmill motor and a preparation method thereof, belonging to the field of motors. And it is widely used in the medical industry, fitness equipment industry, sports industry and household treadmill motors. Background technique

[0002] A motor brush is a device that transmits energy or signals between the fixed part and the rotating part of a rotating machine such as a motor or generator. Also known as carbon brush. Carbon brushes are generally made of pure carbon and coagulant. They are generally square in shape and are stuck on a metal bracket. There are springs inside to press it tightly on the rotating shaft. part. The carbon brush looks a bit like the rubber strip of a pencil, with wires leading out from the top. There are large and small volumes. Carbon brushes are used on commutators or slip rings as sliding contacts for leading and exporting current, and are wide...
