the selection of brushes is mainly determined by the temperature rise of the brushes and the circumferential speed of the commutator. the temperature rise of the brush is related to the density of the brush and the contact pressure drop of the commutator, the mechanical loss and the thermal conductivity of the brush. if the peripheral linear speed is too high, the brushes and commutators will be heated, the sparks will increase, and the wear of the brushes and commutators will be aggravated.from the point of view to use, the signs of good brush performance mainly include the following situations:1）long life and no wear on the commutator, no scratches, unevenness, burning, wire drawing, etc.2）it has good commutation performance, so that the spark is suppressed within the allowable range, and the energy loss is small;3）when the brush is running, it is not overheated, has low noise, is no damaged, no changed color, not burn;4）during operation, a uniform, moderate and stable oxide film can be quickly formed on the surface of the commutator.

why does silicone cause carbon brush wear in dc motors? while it's not completely known, the three major theories are abrasive wear, oxidation, or dry film..
direct current (dc) motors are used extensively throughout the pulp and paper industry. these motors are used in various applications such as fan pumps, press and winder motors. the maintenance requirements of the motors are different for each application. an important maintenance function regularly performed is the inspection of carbon brushes and commutators. carbon brushes are critical to the operation of the paper machine with dc motors. worn or failed brushes can make a paper machine inoperable and cost thousands of dollars per hour. this paper discusses the different theories used for carbon brush application in the paper industry. the strength and weaknesses of each brush application theory are also addressed. in the end the "black magic" of carbon brushes is revealed. the goal of this paper is to educate new and old maintenance personnel on carbon brush and commutator performance criteria and upkeep, hence reducing overall maintenance cost.
