to make contact with the brushes and transfer the current to the appropiate windings in the armature.
Another AnswerA commutator is a rotary reversing switch. It's function is to reverse the direction of the current through the rotor windings as they rotate, to ensure that the current direction around the windings remain in the same direction relative to the magnetic field, so that the torque always acts in the same direction.

Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
How does a DC brushless motor work?
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.

Why are the brushes of DC motor motor made of carbon rather than copper?
Carbon is much stronger and because the motor commuter is spinning copper brushes will wear off quickly.
