1.	At what angle with respect to the interpolar axis does the flux tube gives a good approximation?(a) 30°(b) 45°(c) 60°(d) 90°The question was posed to me in quiz.I'd like to ask this question from No Load Current topic in portion Three Phase Induction Motor of Design of Electrical Machines
Answer» Right answer is (c) 60° To EXPLAIN: The flux tube crossing the air gap at 60° from the interpolar AXIS will always GIVE a good approximation. The calculation of the magnetizing MMF should be based upon the value of the flux DENSITY at 60° from the interpolar axis.
