1. An electric motor stator or rotor comprising multiple segments each comprising a bundle of a plurality of individual wires and/or strips comprised of soft magnetic material wherein the multiple segments are disposed side-by-side to form a stator or rotor cylinder array, wherein the wires and/or strips of each bundle are shaped to provide a U-shaped bundle that comprises a relatively long first radially extending region and second radially extending region integral with a relatively short connecting region to form wire and/or strip magnetic flux pathways in each segment and wherein the first radially extending region and second radially extending region of respective neighboring segments of the stator or rotor array receive and share a coil winding to provide two wire coil windings for each stator or rotor segment.
