Question

What is the relation of the stator slot leakage factor with the skew leakage reactance?

(a) skew leakage reactance is directly proportional to the stator slot leakage factor

(b) skew leakage reactance is indirectly proportional to the stator slot leakage factor

(c) skew leakage reactance is directly proportional to the square of stator slot leakage factor

(d) skew leakage reactance is indirectly proportional to the square of stator slot leakage factor

The question was asked during a job interview.

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

Answer 1

The correct option is (a) skew leakage reactance is directly proportional to the stator slot leakage factor

The explanation is: Skew leakage reactance is one of the parameters used in the leakage reactance calculation. The skew leakage reactance is directly proportional to the stator slot leakage reactance.
