Question

what is two layer windings​

Answer 1

Explanation:

A two layer chord winding for an electric machine having a plurality of slots for receiving windings, each of said slots being of the same depth, sized to accommodate two slot layers of full coils and being equally spaced, comprising, for each phase circuit in the machine.

Answer 2

Answer:

A two layer cord winding for a three phase electric machine in which each of the three winding circuits comprise coils with a number of turns which fill a slot layer along with other coils which have a reduced number of turns and do not fill a whole slot layer. In slots wherein the coils with a reduced number of turns are located, the remaining space is filled by a coil with reduced turns from another of the three circuits of the three phase machine
