What conditions should be paid attention to when replacing a brushless DC motor?

Release date:2020-05-20 Author: kf Click:

As an important part of a DC motor, brushes will wear out after a long time of use. If the wear is severe, it needs to be replaced.

1. Because the hardness and current density of different types of brushes are different, the same type of brushes should be used when replacing.

2. When replacing Shuangpin brushes, pay attention to the replacement sequence, the slope is the same, to prevent the brush bounce and affect the commutation.

3. When replacing a single brush, it can be used directly without grinding, but if there are more than 2 brushes on the same brush arm that need to be replaced, grinding is required.

4. When replacing, grind the new brush to the same arc size as the old brush.
