Question

What is the use of split ring commutator in a DC motor?

1 point

a) To ensure good contact between the stationary components and the moving components.

b) To allow the coil to rotate continuously.

c) To ensure the unidirectional flow and current.

d) To prevent the wires from getting entangled.​

Answer 1

Answer:

The split ring has the function of reversing the current at that point. When a dc motor shaft comes into contact with a split ring, the split ring reverses the current to maintain the shaft torque in a magnetic field.

Answer 2

Answer:

Split ring commutator function in dc motor:

The split ring has the function of reversing the current at that point. When a dc motor shaft comes into contact with a split ring, the split ring reverses the current to maintain the shaft torque in a magnetic field.
