Question

What is the formula for the total stator copper section for main winding?

(a) total stator copper section for main winding = number of turns in the running winding * area of the running winding conductor

(b) total stator copper section for main winding = 2 * number of turns in the running winding * area of the running winding conductor

(c) total stator copper section for main winding = number of turns in the running winding / area of the running winding conductor

(d) total stator copper section for main winding = 2* number of turns in the running winding / area of the running winding conductor

The question was posed to me in quiz.

My question is based upon Design of Rotor in portion Design of Single Phase Induction Motor of Design of Electrical Machines

Answer 1

Correct answer is (b) total stator copper section for main winding = 2 * number of turns in the running winding * area of the running winding conductor

Explanation: First the number of turns in the running winding is calculated along with the area of the running winding conductor. On substitution it gives the total stator copper section for main winding.
