Abstract

The invention provides an electric brush for a treadmill motor. An electric brush preparation method comprises steps that matrix powder materials and a binder solution are mixed uniformly to prepare an electric brush raw material mixture; the electric brush raw material mixture is dried and crushed to acquire electric brush raw material powder; the electric brush raw material powder is added to a pressing die to carry out pressing processing to acquire an electric brush blank; thermal curing processing on the electric brush blank is carried out to acquire a half-finished electric brush product; finished product processing on the half-finished electric brush product is carried out to acquire a finished electric brush; the matrix powder materials comprise graphite, polyphenyl ester resin, polytetrafluoroethylene and metal powder. The electric brush has advantages of proper electrical resistivity, good wear-resisting performance, good commutation performance and low spark grade and further has more important advantages of high efficiency, low noise and good product stability.

Description

technical field [0001] The invention relates to an electric brush for a treadmill motor, in particular to an energy-saving 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 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 are becoming more and more diverse, so various types of bru...
