What is the primary functions of the springs in a Dc motor's brush assembly?

The primary function of the springs in a DC motor's brush assembly is to provide constant pressure on the brushes against the commutator. This pressure ensures good electrical contact between the brushes and the commutator, allowing for efficient transfer of electrical current and smooth operation of the motor. The springs also help to absorb any vibrations or fluctuations in the motor's operation, helping to maintain a consistent and reliable performance.

- To maintain contact between the brushes and the commutator.
- To provide a path for the current to flow from the brushes to the commutator.
- To absorb vibration and noise.
