What is the function of inter pole in DC generator?
A. To serve the economical aspects.
B. To neutralize the distortion of main field flux due to armature reaction.
C. To get a superior commutation.
D. Both B and C.
Answer: D
Share your understanding of this question with the correct explanation.
The function of an inter-pole in a DC generator is to neutralize the distortion of the main field flux caused by armature reaction and to improve the commutation process.
Armature reaction refers to the effect of the armature current on the main field flux in a DC machine. The armature current creates a magnetic field that interacts with the main field flux, causing distortion. This distortion can lead to poor commutation, resulting in sparking and brush wear.
The inter-pole, also known as the commutating pole, is an additional pole placed in between the main poles of the generator. It is specifically designed to counteract the armature reaction. The inter-pole produces a flux that opposes the armature reaction, helping to neutralize the distortion of the main field flux and improve the commutation process.
By neutralizing the armature reaction and improving commutation, the inter-pole ensures smoother operation, reduced sparking, and improved overall performance of the DC generator.
Therefore, option D, “Both B and C,” is the correct answer.
