Question

What is the value of specific electric loading for the salient pole alternators?

(a) 20,000-40,000 A per m

(b) 50,000-75,000 A per m

(c) 25,000-40,000 A per m

(d) 20,000-45,000 A per m

I had been asked this question in class test.

Question is taken from Synchronous Machines Output Equation topic in section Design of Synchronous Machines of Design of Electrical Machines

Answer 1

Right choice is (a) 20,000-40,000 A per m

Explanation: The value of specific electric loading for the salient pole alternators is 20,000-40,000 A per m. The value of specific electric loading for the turbo alternators is 50,000-75,000 A per m.
