1.	What is the range of the flux density in the teeth at no load?(a) 1.7-1.8 Wb per mm^2(b) 1.3-1.5 Wb per mm^2(c) 1.3-1.6 Wb per mm^2(d) 1.4-1.6 Wb per mm^2This question was posed to me in an interview for job.This intriguing question comes from Slot Dimensions in portion Design of Synchronous Machines of Design of Electrical Machines
Answer» Correct option is (a) 1.7-1.8 WB per mm^2 For explanation I would SAY: The minimum value of the flux density in the teeth is given to be 1.7 Wb per mm^2. The MAXIMUM value of the flux density in the teeth is given to be 1.8 A per mm^2.
