What situations should be noted when replacing a brushless DC motor.

Electric brushes, as an important part of DC motors, will experience wear and tear over time. 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 brush should be selected for replacement.

2. When replacing the dual brush, attention should be paid to the order of replacement, with consistent sloping surfaces to prevent brush jumping and affecting commutation.

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