Abstract: A device for positioning the ends of at least first pair of legs of hairpin conductors extending from a stator core with respect to a welder tool includes a first clamping element and a second clamping element that are independently moveable radially. The first clamping element has a first clamping surface and said second clamping element has a second clamping surface, wherein the clamping surfaces radially face each other. The clamping elements form a first radially inner receiving section between the first clamping surface and the second clamping surface, having a first radial width dimensioned to axially receive and clamp a first pair of legs during welding, and a second radially outer receiving section inside the first and second clamping elements, having a second radial width dimensioned to receive at least a further pair of legs during welding of the first pair of legs.

Abstract: Methods for repairing electric machines, such as wind generators, and stators implemented thereof. One method includes replacing a first stator core with a second stator core, wherein the second stator core has fewer stator slots than the first stator core, and wherein the stator slots are configured to receive coil windings. The method includes increasing a number of coil turns forming each coil winding from a first value to a second value, wherein the first value is associated with the first stator core and the second value is associated with the second stator core. The electric machine with the second stator core has rated power output at least as high as the electric machine with the first stator core.

Abstract: A method for the alignment and the compaction of conductive elements of inductive windings of a ferromagnetic core, in which groups of conductive elements are accommodated beforehand in respective slots of a ferromagnetic core, keeping corresponding free ends of the elements protruding from a terminal opening of each slot, the method includes the following steps: clamping each group of conductive elements in order to align the respective free ends according to a radial direction, using alignment elements; clamping each group of conductive elements in order to compact the respective free ends according to a radial direction, using compaction elements; and removing either the alignment elements or the compaction elements to a distance from the ferromagnetic core that is greater than the operating space occupation of the apparatuses for coupling heads of free ends of each group of conductive elements.

Abstract: An alignment device of conductive elements which comprises a frame temporarily supporting a ferromagnetic core comprising slots on the inner circumference and able to accommodate a plurality of conductive elements. Each conductive element has hairpin shape or two straight portions and a bridge portion, whereby each straight portion comprises a terminal with an free end front; the device comprises a pusher attached to movement elements, providing a programmable and predefined stroke, movable between a first position of maximum distance from the ferromagnetic core and a second position of minimum distance; a flat surface of the pusher is facing the terminal fronts, if core and pusher are in first position; the flat surface abuts and bends the fronts if core and pusher are in second position.

Abstract: The cold pressure welding apparatus includes a first holding part capable of sandwiching a first flat conductor, a second holding part disposed opposite to the first holding part and capable of sandwiching a second flat conductor, and a drive part for moving the first holding part and the second holding part. The drive part can move the first holding part and the second holding part between a first direction separated position and a close position along a first direction. The drive part can move the first holding part and the second holding part between a second direction separated position and a sandwiching position along a second direction.

Abstract: A method of magnetising or demagnetising an annular component for a rotary machine, a flux arrangement for performing a magnetising or demagnetising method, and a flux assembly for such a flux arrangement; wherein, the annular component includes an alternating arrangement of radial elements and angular elements for forming a Halbach array. A magnetizer is caused to induce magnetic flux in a primary set of elements of the annular component including a primary radial element and an adjacent primary angular element. A shield element shields a secondary angular element of the annular component from magnetic flux from the magnetizer.
