What should I pay attention to when replacing the brushes of micro motors?

Long-term usage of the micro brush motor will wear out the brushes, which should be replaced in accordance with the manufacturer's instructions. The issues that must be addressed when changing the micromotor brushes are described in the paragraphs that follow.

1. When replacing a portion of the micromotor's brushes, make sure all of the micromotor's brushes are from the same brand. The current distribution between the brushes will be unequal if the brush brands are different. All of the machine's brushes must be replaced if brushes with the same rating cannot be matched.

2. Rather than grinding with emery cloth because it will fall into the space between the commutator blades, after replacing the brush on the micromotor, grind the contact surface between the brush and collection ring with glass sandpaper and blow it off with compressed air. The collecting rings and brushes are used in the gap.

3. The spring on the brush holder allows the micromotor's brush pressure to be adjusted, and the range of brush pressures cannot be more than 10% different.

4. To ensure that the brushes and the collection ring work well together, replace more than half of the micromotor's brushes and operate the machine for more than 12 hours before reloading and running.
