What is the formula of the leakage coefficient?
(a) leakage coefficient = total flux * useful flux
(b) leakage coefficient = total flux / useful flux
(c) leakage coefficient = useful flux / total flux
(d) leakage coefficient = total flux + useful flux
I have been asked this question during an interview.
This interesting question is from Modern Trends in Machine Design & Magnetic Leakage in section Fundamental Aspects of Electrical Machine Design of Design of Electrical Machines
