Valid Reasons to Use Carbon Brushes in Motors

The carbon brush is most commonly used in the motors as compared to copper brushes or other fabric brushes. While titan brushes are useful for the cranes and forklifts, carbon brushes prove to be the best for motors. The advantages of carbon brush that makes it useful in the dc motors are listed below.

·   High Melting Point

As compared to other metals, carbon has a high melting point. As the brushes in dc motors are closely linked to the commutator, an increase in temperature causes instability among other metals. But with carbon brushes, stability can be maintained even at high temperatures.

·   Shape Adopting Nature

Even though the carbon brush is available in a rectangular shape, the brush comes with great elasticity. On being fixed near the commutator, the carbon brush can easily adopt the circular shape of the commutator. 

·  Soft Metal

As compared to copper, carbon proves to be a more soft metal. The soft nature of the carbon brush prevents the commutator from being damaged when friction is produced between the brush and the commutator. With the use of copper or other fabric brushes, there are high chances of damage to the commutator because of the hardness of the metal.

·  Self-Lubricating

The self-lubricating ability of the carbon brushes makes it useful for the dc motors. It prevents the requirement of any other lubricating oil or grease for the cooling purpose. The carbon brushes automatically get cooled once the dc motor is turned off.

·  Negative Temperature Co-efficient

The negative temperature co-efficient is another reason to use the carbon brush in dc motors. With a negative temperature coefficient, the resistance gets reduced whenever there is an increase in temperature. Using the carbon brush in the dc motors reduces the chances of damage and offer protection from sparks.

Advantages of using Einhell Carbon Brushes in motors

A pair of carbon brushes

A brush or Evolution Brushes are a device, which conducts current among stationary wires and moving parts, most usually in a rotating shaft. Typical applications comprise electric motors, alternators along with electric generators.

Several types of generators or electric motors to function, the coils of the rotor must be connected to complete an electrical circuit. Formerly this was proficient by affixing a copper or brass commutator or 'slip ring to the shaft, with springs pressing braided copper wire 'brushes' onto the rings which demeanour the current. Such brushes offer poor commutation as they moved from one commutator section to the next. The cure was the prologue of 'high resistance brushes' made from graphite (sometimes with added copper). Although the conflict was of the order of tens of milliohms, they were high conflict enough to provide a gradual shift of current from one commutator section to the next. The term brush is relics in use.

How the brushes are used?

Accurate work of the brush depends on the application. Graphite/carbon powder is commonly used. Einhell Carbon Brushes is used for better conductance (rare for AC applications and not on automotive fuel pumps that run on carbon commutators). In order to maximize electrical conductivity and green strength, highly dendritic (electrolytic) copper powder is used. Binders, mostly phenol or other resins or pitches, are mixed in so the powder holds its shape when compacted. Other additives comprise metal powders, and solid lubricants like MoS2, WS2. Much expertise and research is needed in order to define a brush grade mixture for each application or motor.

The brush compound is compressed in a tool consisting of upper and lower punch and die, on mechanical or hydraulic presses. In this step, depending on later processing, the copper-wire (called shunt wire) can be inserted repeatedly through a hole in the upper punch also fixed into the pressed brush block by the powder pressed around. This operation, called "tamping", is usually performed using electrolytic copper powder, perhaps with silver coating for some high performance applications. After this progression, the brush is still very fragile and in professional jargon called a 'green brush'.

What is a Carbon Brush?

Carbon brushes appear to be all over the place that is as these are in the motors of many garden and home appliances, across all makes and models. Our guide will help you work out what a carbon brush is, when it requirements replacing, and how to get started on fitting it yourself.
