Question

What is the condition for choosing the armature current/parallel path in armature design?

(a) > 200 ampere for both lap and wave windings

(b) >200 ampere for lap winding, <200 ampere for wave winding

(c) < 200 ampere for both lap and wave windings

(d) <200 ampere for lap winding, >200 ampere for wave winding

This question was addressed to me by my college professor while I was bunking the class.

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

Answer 1

The correct choice is (c) < 200 ampere for both lap and wave windings

For explanation I would say: While designing the armature slots, the armature current should be less than 200 ampere. The armature current should also never cross 200 ampere for the lap winding.
