Abstract: A presently-preferred method of manufacturing a stacked core for a magnetic-induction device comprises cutting a sheet of magnetic material into one or more strips of the magnetic material so that a width of each strip changes along a length of the strip. The presently-preferred method also comprises cutting the strips to form a plurality of laminae having different widths. The presently-preferred method further comprises stacking and bonding the laminae to form a winding leg, an outer leg, or a yoke having laminae of relatively large width positioned at its approximate center, laminae of relatively small width positioned at its outer edges, and laminae of progressively decreasing width positioned between the center and the edges.

Abstract: The invention relates to a transformer winding (10, 40) with at least two hollow-cylindrical winding modules (12, 14, 42, 44), which are nested one inside the other and extend about a common winding axis (16), wherein said winding modules are spaced apart from one another radially (32, 62) within at least one hollow-cylindrical cooling channel (18, 46) arranged between said winding modules by means of strips of insulation (20, 22, 24, 26, 28, 30, 32, 48). The strips of insulation (20, 22, 24, 26, 28, 30, 32, 48) have a cross-sectional form which predominantly avoids a surface profile (50, 52, 54) radially (32, 62) with respect to the winding axis (16).

Abstract: The invention relates to a method for hardening coils (16), which have been manufactured during a winding method, during which a coil (16) is firstly placed inside an oven (12) for hardening. The coil (16) is heated to a predeterminable temperature and is rotated about its longitudinal axis (32) in order to prevent resin from dripping off. The conductor(s) of the coil (16) is/are flown through by current, particularly direct current, and are heated thereby. The invention also relates to a device for hardening coils (16) with which the inventive method can be carried out.

Abstract: The invention relates to a transformer winding (10, 50, 70) comprising at least two hollow-cylindrical, axially adjacent winding modules (12, 14, 52, 54, 72, 74, 76, 78), which are arranged about a common winding axis (16, 56, 80) and have an electrical conductor (18, 20) wound in layers, and a common electrical insulting layer (22, 68, 82), by means of which the winding modules (12, 14, 52, 54, 72, 74, 76, 78) are enveloped. The insulating layer (22, 68, 82) has at least one annular, radial depression (28, 30, 58, 60, 62, 64, 66, 84, 86, 88) or annular, radial elevation (32), which is salient transversely to the winding axis (16, 56, 80) on the radial outer face (24, 90) of said insulating layer (22, 68, 82).

Abstract: The invention relates to a two- or multiphase transformer having a yoke which has a crosspiece and at least two limbs, over which limbs a coil (17) is placed in each case, and having at least one carrier on which the crosspiece is fixed and which has bearing faces (14) for the coils.

Abstract: The invention relates to a ring-shaped core for a power transformer (18), wherein the ring-shaped core extends about an imaginary center axis (70) in the form of a closed toroidal structure and is constituted of a plurality of adjacent layers of sheet metal. The ring-shaped core, along the length of the toroidal structure, is constituted of at least three core section modules (11) that can be connected to and detached from each other, the core section modules being interconnected by an overlap of individual sheet layers and/or sheet layer sections. The invention also relates to the arrangement of ring-shaped cores having winding modules (100). The latter can be arranged in a common connecting structure and every ring core having winding modules (101-103, 111-113, 121 -123) arranged therein can be separately introduced into the connecting structure and removed therefrom in a non-destructive manner.

Abstract: The invention relates to a method for production of a winding block for a coil of a transformer, having at least one winding composed of electrically conductive wire or strip material with a plurality of turns and an insulating layer composed of electrically insulating fiber material with a specific number of windings of the insulating fiber material. The turns composed of electrical conductive material are fitted independently of the turns of the insulating material and, after the predetermined number of turns of electrically conductive material have been fitted, a smaller number of turns of electrically insulating material are fitted over the same section onto these turns of electrically conductive material, such that the remaining number of turns, of electrically insulating material which remain before reaching a number of turns of electrically conductive material are used as edge insulation.
