Abstract: The invention relates to a device and to a method for winding toroidal cores without using a magazine, comprising a toroidal-core retainer and comprising elements that are substantially arranged in a wire-guiding plane and that serve to guide and to magazine wire. The device comprises: a first transport roller and a second transport roller, which are arranged in relation to the toroidal-core retainer in such a way that a wire to be magazined on the transport rollers in the wire-guiding plane and to be wound can be guided between the first and the second transport roller through the toroidal core; a wire ejector arranged adjacently to the second transport roller; and a wire tensioner.

Abstract: A method for manufacturing a cylindrical winding for slotless electrical machine according to the following steps: a) a winding head (211) able to move according to three axes X, Y, Z, winds continuously a wire following a predetermined winding program around two sets of needles (80) on the external surface of a first cylindrical tube (6). The needles are located on the conical shaped end surfaces of two identical cylindrical bodies axially juxtaposed and axially and rotatable movable (R). The cylindrical bodies are partially located inside the first cylindrical tube (6), b) after the achievement of the winding operation of all the electrical machine phases all around the 360° peripheral surface of the first cylindrical tube (6) a second cylindrical tube is put around the achieved winding (41); c) the two sets of needles (80) are taken away and the two cylindrical bodies are axially moved away.

Abstract: In a method for winding an electrical machine, a winding auxiliary body is placed on at least one of the end faces of a base body such as to cover at least one of the slot end openings within a circumferential bridging area. Electrical conductors of a winding system are inserted in at least one of the slots whose slot end opening is on one side of the bridging area and passed through an uncovered slot end opening. Subsequently, the electrical conductors are deflected by the winding auxiliary body and guided to a further uncovered one of the slot end openings on another side of the bridging area. After placement of an end plate having an axially projecting separating element and plugging an axial attachment cutout of the winding auxiliary body onto the separating element, the winding auxiliary body is removed, thereby producing a winding element of the winding system.

Abstract: A toroidal core automatic winding apparatus has a winding ring positioned concentrically around a supply ring. The rings are C-shaped, by virtue of a through-slit on each ring. Wire wound on the supply ring is drawn out towards a toroidal core, via a wire guide on the winding ring. A ring rotation mechanism rotates the supply ring and winding ring in the same direction as that in which the supply ring was rotated when being loaded with the wire, but at mutually different speeds, to wind the wire around the toroidal core. The difference in the rotation amounts of the supply ring and winding ring equals the length of the wire that is wound on the toroidal core.
