Question

The plot between carter’s coefficient and the relative flux density is the carter’s fringe curve.

(a) true

(b) false

This question was posed to me during an interview.

Question is from Field Form, Harmonic Analysis of Flux Distribution Curve in division Principles of Magnetic Circuit Design of Design of Electrical Machines

Answer 1

Correct option is (a) true

To elaborate: Carter’s fringe curves is one of the techniques used in the plotting of the field form in the salient pole machines. The plot between carter’s coefficient and the relative flux density is called as carter’s fringe curve.
