1. On the same motor, in principle, should use the same type of carbon brush, but individual reversing particularly difficult for large and medium-sized motor, can use the twin carbon brush, the slide to the side with good lubrication performance, sliding out side used to suppress the spark ability of carbon brush, so that the operation of the carbon brush is improved.
2. To ensure that within a carbon brush into the brush can be free to move up and down, the clearance between the carbon brush and brush wall between 0.1 0.3 mm, in order to avoid carbon brush and brush for clearance is too large to produce. The lower edge of the brush from the commutator surface distance should be kept at about 2 mm. If distance is too small, easy to brush touch commutator, distance is too large, carbon brush is easy to vibrate and cause damage.
3. In the same electric motor to various carbon brush of unit pressure evenly, so as not to electricity
