ABSTRACT:
An annular coil assembly includes a multi layer coil having a wound-over portion in which an upper winding layer is wound over a lower winding layer, and a non-wound-over portion in which each turns of the upper winding layer is housed between two adjacent turns of the lower winding layer. The ratio of plastic deformation of the wire in the wound-over portion and adjacent areas thereof is less than that of the wire in the non-wound-over portion.
