What is the function of the Commutator For Power Tools?

The commutator in power tools serves several important functions:

1. Direction Control: 

It reverses the direction of current flow in the armature windings as the tool rotates. This allows for the continuous rotation of the motor in one direction.

2. Current Switching: 

The commutator ensures that the current is switched to the appropriate windings in the armature at the right time. This switching action maintains torque and efficiency during operation.

3. Voltage Regulation: 

By controlling the timing of current application to the windings, the commutator helps regulate the voltage across the motor, ensuring consistent performance.

4. Brush Contact: 

It provides a surface for the brushes to make contact with the armature, allowing for the transfer of electrical current necessary for motor operation.

In summary, the commutator plays a crucial role in the operation of DC motors used in power tools, enabling effective and efficient performance. If you need more detailed information or specific applications, let me know!
