(a) true

(b) false

The question was asked in an interview.

This question is from Design of Armature in chapter Thermal Design Aspects of Electrical Machines & D.C of Design of Electrical Machines

Answer 1

The correct answer is (a) true

To explain I would say: The number of coils chosen for the armature slot design should always be minimum in number. This is because the machine cost reduces and it becomes cost efficient.
