What is the role of split ring in an electric motor?

Question

Answer

Split ring plays the role of commutator in an electric motor. The commutator reverses the direction of the current flowing through the coil after each half rotation of the coil. Due to this reversal of current, the coil continues to rotate in the same direction.

Answer

Split ring is used for changing the direction of current in the coil. After every half rotation in a coil the direction of the rotating coil remains same and the coil  rotates in the same direction.

Answer

Role of Split Ring in an Electric Motor:

The split ring is an essential component of an electric motor. It is also known as a commutator. The commutator is a metal ring with a split in it, and it rotates with the armature coil of the motor. The split ring is responsible for changing the direction of the current flow in the armature coil. The role of the split ring in an electric motor is discussed in detail below.

1. To change the direction of the current:
The split ring is responsible for changing the direction of the current in the armature coil. As the split ring rotates with the armature coil, the brushes on either side of the split ring make contact with the different parts of the ring, which reverses the direction of the current flow.

2. To produce a constant torque:
The split ring helps in producing a constant torque in the electric motor. As the direction of the current in the armature coil changes, the magnetic field also changes, which results in a constant torque being produced.

3. To ensure smooth rotation:
The split ring ensures smooth rotation of the armature coil. As the current in the coil changes direction, the magnetic field also changes, which results in a smooth rotation of the armature coil.

4. To prevent sparking:
The split ring also prevents sparking in the electric motor. As the brushes make contact with different parts of the split ring, it ensures that the current flows smoothly without any sparking.

Conclusion:
In conclusion, the split ring is an essential component of an electric motor. It is responsible for changing the direction of the current flow in the armature coil, producing a constant torque, ensuring smooth rotation, and preventing sparking. Without the split ring, the electric motor would not function properly.

Answer

*The split ring in the electric motor also known as a commutator reverses the direction of current flowing through the coil after every half rotation of the coil. Due to this the coil continues to rotate in the same direction.

Answer

The split-ring in an electric motor reverses the direction of current in the armature coil of the motor. Therefore, the direction of the force acting on the two arms of the coil is also reversed. As a result of this, the coil of D.C. motor continues to rotate in the same direction.
