Question

What is the relation of the overhang leakage reactance with the average coil span in slots?

(a) overhang leakage reactance is directly proportional to the square of the average coil span in slots

(b) overhang leakage reactance is indirectly proportional to the square of the average coil span in slots

(c) overhang leakage reactance is directly proportional to the average coil span in slots

(d) overhang leakage reactance is indirectly proportional to the average coil span in slots

The question was posed to me in a job interview.

Origin of the question is Parameters in portion Design of Single Phase Induction Motor of Design of Electrical Machines

Answer 1

Right choice is (c) overhang leakage reactance is directly proportional to the average coil span in slots

Explanation: The overhang leakage reactance is one of the parameters used in the leakage reactance calculation. The overhang leakage reactance is directly proportional to the average coil span in slots.
