Because the quality of the brushes and the reasonable matching are one of the important factors affecting the size of the spark in the commutator operation. Carefully inspect the replacement brushes. It is best to use a new set of brushes with the same model, size and size as those produced by the same manufacturer of the motor. The connection between the brush and its braided wire should be firm and reliable, and there should be no poor contact and looseness. The well should be covered with an insulation sleeve in the braided wire L sleeve. The brush and the commutator should have good contact, and its contact surface should be not less than 75 ft of the brush cross section, and the brush must not have any missing corners or cracks.
Each brush that is replaced should be electrically measured, and brushes with equal or similar limits should be paired for parallel use to ensure that the current between the parallel brushes can be evenly distributed. Only by mastering these related skills can the performance of the commutator be better. Now, in order to meet more needs, there are many such product specifications and models, such as flat type, pneumatic type, and structural design. These different types of products have the same good performance properties, and they have good abrasion resistance.
