Instructions for use of brushes

1. In order to ensure the normal operation of the motor, it is very important to select the brush type accurately. Due to the different raw materials and technologies used in the production of brushes, their technical functions are also different. Therefore, when choosing a brush, we should think about the function of the brush and the request of the motor to the brush. The symbol of the outstanding function of the brush should be:

The role of carbon brushes

The role of carbon brushes

The definition of carbon brush: carbon brush out of context, is made of carbon (that is, graphite, but some use alloy (sheet) instead of graphite carbon brush). The carbon brush is a component on the surface of the phase changer in the brushed motor. When the motor rolls, the electric energy is transmitted to the coil through the phase changer, because its primary component is carbon, called carbon brush, which is easy to wear. Should be punctual maintenance and replacement, and pick up the accumulation of carbon brush.

Common knowledge of carbon brushes for electric tools

The fan on the armature rotates to draw outside air in through the vents, and the rotating fan then allows the air to flow through the interior space of the motor to cool the motor. 2. Capacitors for noise suppression When electric things equipped with series motors are used, sparks will occur in the commutator and carbon brush of the motor, which will disturb radios, televisions, medical equipment, etc. It is necessary to suppress capacitors and anti-current coils on electric things to play an anti-jamming role.

How to choose carbon brushes for electric tools

Power tools carbon brush-brush type selection use 1. in order to ensure the normal operation of the motor, accurate selection of brush type is very important, because the manufacturing of carbon brush when the selection of raw materials and technology is not the same, its technical function is also different. Therefore, in the choice of carbon brush, we should think about the function of carbon brush and the motor's demand for carbon brush. The carbon brush must be installed in the brush holder to ensure that it can move up and down leisurely. The vacancy between the carbon brush and the inner wall of the brush holder is between 0.1-0.3mm, so as to prevent the carbon brush and the brush holder from shaking due to excessive vacancy. The distance between the margin under the carbon brush and the outer surface of the commutator should be kept at about 2mm. If the distance is too small, brush

Fault Diagnosis of Carbon Brush of Electric Tools

Fault Diagnosis of Carbon Brush of Electric Tools

The wound weapon used on the motor often has several batches of carbon brushes than the moving tool. Why does the wound carbon brush on the motor emit sparks: when we use the carbon brush of the wound motor, due to the continuous wear of the carbon brush during the long-term operation, the occurrence of uneven contact surface, the pressure of the carbon brush may not be that the collector ring is not round, and there are oil droplets or other debris on the bearing falling between the collector ring and the carbon brush, etc., which will all constitute sparks from the carbon brush of the power tool.

Possible Problems of Carbon Brush of Electric Tools in Operation

Possible Problems of Carbon Brush of Electric Tools in Operation

Carbon Brush of Electric Tool-Questions and Elements that Carbon Brush May Present in Unit Work 1. Carbon Brush of Electric Tool Wear Severe. The main elements that constitute the severe wear of carbon brushes are the following: a. the smoothness of the surface of the slip ring. The higher the surface finish of the slip ring, the smaller the conflict coefficient, the lower the wear rate of the carbon brush; B. The influence of the carbon brush data. Different manufacturers, different types of carbon brush composition structure is not the same, the wear rate is not the same. Selecting the same kind of carbon brush can reduce the imbalance of the wear rate of the carbon brush itself, so the carbon brush with the same trademark should be selected when replacing the carbon brush; C. the influence of spring pressure. If the tension spring pressure is too large, it will structure
