The split rings cause the direction of the magnetic field in the armature to change direction as the motor rotates. If this didn't happen the motor would not rotate.
Slip rings can be used for an AC motor which causes the direction of the magnetic field to change with the AC waveform.

∙ 11y agoin dc motors commutator is required to convert from alternating quantity to unidirectional quantity. to explain this commutation process in a simple way split rings are used..
in ac to collect the current from the armature slip rings are used.

How does the commutator reverse the current in a motor?
Commutator is a split ring which reverses the current .when the commutator turns around due to magnetic force and because of it even the current gets reversed
What is the purpose of using slip rings?
This is the standard answer for both split ring commutator and slip ring. A split ring commutator is to reverse the current direction through an armature every half turn A slip ring is to ensure that the current continue to flow to the external circuit Last bit of additional information. Carbon brush ensure that the slip ring are in contact with the circuit containing the external load *Note: Do not get confused with split ring commutator(d.c.generator) & slip ring(a.c. generator)
Switch that regularly reverses the current in some motors?
A switch that reverses the direction of the current in a motor is called a forward reverse drum switch. It is a single phase motor that turns from clockwise to counter clockwise.
What happens if commutator of DC generator is removed?
If the commutator is removed from your generator, you (if you connect slip rings) get AC supply instead of DC supply. the function of the commutator is to convert AC to DC supply and vice versa.Additional AnswerRemoving the commutator will also prevent you from connecting the output of the generator to its load. Remember, the generator's armature is spinning!
What does the commutator in an electrical motor do?
If there is a commutator, it means you are dealing with a DC motor.The commutator acts like a switch to supply voltage to a revolving armature from the stationary brush assembly.A commutator has commutator bars, each seperated by mica insulation. Each coil of the rotating armature is connected to two bars that are in directly opposite positions across each diameter of the armature.The total number of commutator bars depends on the design of the windings on the armature: either "lap" or "wave" windings can be used on a DC motor or generator which is provided with a commutator.For more information see the answer to the Related question and also the Related link shown below.

What does the split ring commutator do in a motor?
It generates a alternating current to keep the motor rotating in the same direction.
How can you generate a DC?
U sohuld replace the slip-ring which it is in the AC generator to a commutator. It is a split-ring. Then u can produce DC generator.
Function of a commutator?
it serves as a mechanical rectifier

How is current alternated?
It's the natural output from a coil that rotates within a field. To produce d.c. requires the natural a.c. output to be rectified (usually by means of a split-ring commutator).
What is a reversing switch that rotates with the coil in am electric motor and reverses the direction of the current every half turn?
It's called a 'split-ring commutator'. It changes the naturally-produced a.c. into d.c.
How does torque reverse in a dc motor after half a revolution?
The point is that, with a d.c. motor, we don't want the torque to reverse every half-revolution, if the motor is to continue running in the same direction. To achieve this, we use a split-ring commutator/brushes, which rotates with the armature coil. Essentially, a split-ring commutator has twofunctions: (1) to enable us to connect the rotating coil to an external supply circuit and (b) to act as a rotating switch, ensuring that the armature current always flows in the same direction relative to the motor's magnetic field. Thanks to (b), the machine will continue to rotate in the same direction.Without a split-ring commutator, after half a revolution, the armature current will reverse direction relative to the magnetic field, the torque will reverse, and the motor will reverse direction.
Do split rings convert AC to DC power in DC motor?
no they do notAnswerYes, a split-ring commutator does convert a.c. to d.c. It is a rotary switch fitted to the shaft of the generator, which reverses the polarity of its output every half-cycle, so that the generator's output is a pulsating d.c. instead of a.c.

Purpose of slip rings?
slip ring is connect on shaft of motor to collect current from commutator without any complicate connection and with use of it resistors can be insert in circuit and therefore speed control of motor can easily achive
