Dewalt N309479 Brush Ring Assembly for Impact Driver

The Dewalt N309479 Brush Ring Assembly operates as a positional and holding part of motor brushes in impact drivers and wrenches. It secures the brushes to the motor commutator, and the brushes are balanced in contact with the electrical contact. As the brushes are damaged, the assembly ensures that the brushes are aligned properly and at a proper pressure to ensure that the current flows into the motor in a consistent flow. It is installed in the motor frame, where it facilitates constant production of torque and accurate impact action. Its role is in averting power interruption and electrical inefficiency in high-load and repetitive-use operations in its fastening or loosening.
