Question

What is the formula for the winding height in the design of the field windings?

(a) winding height = height of the pole – height of shoe + space taken by the spool, flanges, etc

(b) winding height = height of the pole + height of shoe + space taken by the spool, flanges, etc

(c) winding height = height of the pole + height of shoe – space taken by the spool, flanges, etc

(d) winding height = height of the pole – height of shoe – space taken by the spool, flanges, etc

I have been asked this question during an interview for a job.

Question is from Design of Field Winding topic in chapter Design of Synchronous Machines of Design of Electrical Machines

Answer 1

Right choice is (d) winding height = height of the pole – height of shoe – space taken by the spool, flanges, etc

Explanation: The height of the pole and the height f the shoe is calculated. Next the space taken by the spool, flanges is calculated and the winding height is obtained.
