What is the total ampere conductors/pole (in SI) if 600 lap wound conductors carry 120A current through conductors (P=4)?

(a) 18000

(b) 9000

(c) 4500

(d) 13500

The question was posed to me in a job interview.

This intriguing question originated from Armature Reaction topic in division Armature Reaction of DC Machines

Best answer
Correct option is (a) 18000

Best explanation: Ampere-conductors/pole =ZIc/P= Zla/AP. Ampere conductors per pole is calculated by multiplying total no. of conductors with the current carried by them divided by the total no. of poles.

Ampere-conductors/pole = 600*120/4 =18000.
