b) Pulsational loss decreases with an increase in air gap length
B.
b) Pulsational loss decreases with an increase in air gap length
Answer: b
Answer: b
Explanation: The change in air gap flux density is small when the length of the air gap is
increased. This is due to slotting. The pulsational loss in the pole face decreases with an
increase in air gap length.
b
Explanation: The change in air gap flux density is small when the length of the air gap is increased. This is due to slotting. The pulsational loss in the pole face decreases with an increase in air gap length.
