Question

What is the relation of the zigzag reactance with the specific permeance for zigzag leakage?

(a) zigzag reactance is directly proportional to the specific permeance for zigzag leakage

(b) zigzag reactance is indirectly proportional to the specific permeance for zigzag leakage

(c) zigzag reactance is directly proportional to the square of the specific permeance for zigzag leakage

(d) zigzag reactance is indirectly proportional to the square of the specific permeance for zigzag leakage

The question was asked by my college director while I was bunking the class.

This intriguing question comes from Parameters topic in chapter Design of Single Phase Induction Motor of Design of Electrical Machines

Answer 1

Correct answer is (a) zigzag reactance is directly proportional to the specific permeance for zigzag leakage

Easy explanation: Zigzag reactance is one of the parameters used in the leakage reactance calculation. The zigzag reactance is directly proportional to the specific permeance for zigzag leakage.
