The complete winding outline of a rotor, including the forward as well as the return conductor of the winding loops are applied, in flat form, to a flexible sheet, as a printed or laminated conductor. The flexible sheet has a fold line, across which the conductor portions forming the coil ends extend. The sheet is then folded along the fold line upon itself and rolled into a hollow cylinder, to form a self-supporting rotor. If desired, an internal support of a plastic, metal tube, or the like can be applied Multiple-layer windings can be formed by first applying the winding outline to the sheet, and then folding the sheet-zig-zag upon itself with additional insulating layers where conductors would contact each other, and then rolling the folded sheet with the conductors thereon into a cylinder.
