    The split ring commutator reverses the flow of current every half-turn.
    If this did not happen, the torque generated by the current's movement
    through the magnetic field would simply hold the motor in place, which
    is the opposite of what you want to happen.

    Reversing the current, with a small period of time where no current is
    flowing, allows the armature to keep spinning, with the torque now
    pushing it in the correct direction.

    A commutator is the moving part of a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit.
