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.
Does the alternating current supplied to the armature winding of a DC motor gets converted to dc by a commutator before it flows through the armature coil of the DC motor?
The commutator is a rotating switch, which reverse the polarity of the generated voltage every half-cycle. So it acts to rectify the output voltage.
Is a commutator the rotating element of a motor?
The commutator is part of the armature on a DC motor and this assembly is the rotating element of a motor.
In a motor electrical current enters through the brushes?
In a motor, electrical current enters through the brushes, which are in contact with the commutator. This flow of current energizes the motor's windings, generating a magnetic field that interacts with the stator's magnetic field. This interaction produces torque, causing the rotor to spin and ultimately driving the mechanical load connected to the motor. The design of the brushes and commutator allows for the continuous transfer of current, enabling smooth motor operation.

What is the definition of commutator?
A commutator is an electrical switch that periodically reverses the current direction in an electric motor or electrical generator. A commutator is a common feature of direct current rotating machines.
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.

What is the function of the commutator in a starter?
The commutator in a starter motor serves to reverse the direction of current flow in the motor windings as the rotor turns. This reversal ensures that the torque produced by the motor remains in one consistent direction, allowing the rotor to spin and start the engine. Additionally, the commutator helps maintain a continuous electrical connection between the stationary brushes and the rotating armature. This functionality is crucial for the efficient operation of the starter motor.

What does the split ring commutator do in a motor?
It generates a alternating current to keep the motor rotating in the same direction.
What is the purpose of a commutator in a dc motor?
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.
