DC Motor Commutator Quiz

The commutator's role is to reverse the current direction in the coil.

The commutator achieves this by switching the connections between the coil and the external circuit as the coil rotates.

Reversing the current direction in the coil is essential for continuous rotation because it ensures that the magnetic field generated by the coil remains aligned with the magnetic field of the stator.

<p>When the coil becomes vertical and the commutator gaps align with the brushes, the current in the coil briefly stops flowing.</p> Signup and view all the answers

<p>The commutator ensures continuous clockwise rotation by consistently reversing the current direction in the coil, maintaining a constant interaction between the rotor's magnetic field and the stator's magnetic field.</p> Signup and view all the answers

<p>The commutator directly influences the direction of current in the coil. The direction of current, in turn, determines the direction of torque produced by the coil.</p> Signup and view all the answers
