A laminated winding for electric machines comprises a cylinder formed of a roll of conductive strip-like material isolate on one side and having a roll wall. The cylinder includes axial slots across the roll wall alternatively starting from the one roll end and from the other roll end and extending nearly up to the opposite roll end leaving a circumferential portion and so as to form a wave winding. The laminated winding further comprises electrical terminals for supplying an electrical current through the wave winding. Preferably, the axial roll portion between the slots and the circumferential roll portions are of equal width. A first one of the windings may be arranged as a rotor and a second one of the windings may be arranged as a stator of a rotating electric machine.
A plurality of laminated windings for an electric machine, each of said laminated windings comprising a cylindrically formed roll of conductive strip-like material isolate on one side and having a cylindrical surface concentric about a cylindrical axis, said cylindrically formed roll having axial slots formed in the cylindrical surface alternatively starting from one roll end and from another roll end, respectively, and extending nearly up to the respective opposite roll end, leaving a circumferential roll portion and forming a laminated winding with three quarter windings, said laminated winding further comprising electrical terminal means connected to said laminated winding with three quarter windings for supplying an electrical current therethrough, said electric machine comprising a rotating electric machine, a first one of said laminated windings being arranged as a rotor, and a second one of said laminated windings being arranged as a stator.
