Question

What is the range of leakage coefficient for output of 100kW?

(a) 1.12-1.25

(b) 1.11-1.22

(c) 1.10-1.20

(d) 1.11-1.15

The question was posed to me during an online interview.

Question is from Pole Design topic in division Thermal Design Aspects of Electrical Machines & D.C of Design of Electrical Machines

Answer 1

Right answer is (b) 1.11-1.22

For explanation: 1.12-1.25 is the leakage coefficient when the output is 50kW. 1.10-1.20 is the leakage coefficient when the output is 200kW.
