What is the relation between reluctance, flux and mmf of the machine?(a) low reluctance, less flux leakage, high mmf(b) low reluctance, high flux leakage, high mmf(c) high reluctance, high flux leakage, low mmf(d) high reluctance, less flux linkage, high mmfThe question was asked during an online exam.I want to ask this question from Modern Trends in Machine Design & Magnetic Leakage topic in section Fundamental Aspects of Electrical Machine Design of Design of Electrical Machines

Answer»

Correct choice is (a) low RELUCTANCE, less flux leakage, high mmf

Easiest explanation: The designer’s problem is to provide a path of low reluctance to that of comparatively little flux leaks AWAY. In order to COMPENSATE for the flux leakage, high mmf is MAINTAINED.
