Abstract
A coil for a variable transformer is provided having multiple layers of wire. Winding of such a coil is facilitated by providing an end form having a series of raised fins, or partitions, between which stacked layers of wire are held. The construction provides for easy and economical machine-winding and ensures that the segments of wire forming the commutating surface are held relatively immovable with respect to each other, thus preserving the integrity of the commutating surface.
