Question

What is the value of space factor for the strip on edge winding?

(a) 0.8-0.9

(b) 0.4

(c) 0.65

(d) 0.75

I had been asked this question by my school principal while I was bunking the class.

This interesting question is from Design of Rotor in portion Design of Synchronous Machines of Design of Electrical Machines

Answer 1

The correct option is (a) 0.8-0.9

The best explanation: The space factor for the strip on edge winding is 0.8-0.9. The space factor for small round wires is 0.4 and for large round wires it is 0.65. The space factor for large rectangular conductors is 0.75.
