Abstract: The invention concerns a method of dismantling a cooling tube (1) of polymer material and an elongate cutting tool used in said method. According to the method said tube (1) being fixed in an axially running cooling duct (2) in a stator tooth (3) of a stator (4) of a high-voltage rotating electric machine is cut at an axial level close to the stator (4) at both ends of the stator tooth (3). Then the cutting tool having a radially protruding cutting edge is inserted into the cut tube (1) at one of said ends, said tool being forced through the tube (1) along said duct (2) thereby slitting the tube (1) from inside. Thereafter the slit tube (1) is pulled out of the duct (2) with a twisting movement that causes breakage of the tube wall along the slit (7) and thus reduction of the tube diameter.

Abstract: A rotating electric machine, comprising a stator (1) wound with high voltage cable and provided with stator teeth (4) extending radially inwards from an outer yoke portion (23), wherein at least one stator tooth (4) in a tooth sector (18) is provided with at least one axially running cooling duct (24) connected to a cooling circuit (25) in which coolant is arranged to circulate and in that the axially running cooling tube (24) is connected at least at one end of the stator (1) to a clamping means (27, 28) for axial compression of the stator (1).

Abstract: The present invention relates to a mounting device (80) for reducing short-circuiting forces that are transmitted from a stator core to a stator body in a rotating electric machine comprising a stator with windings drawn through slots in the stator, wherein the stator core is composed of a number of packs (82), each of which includes a number of metal sheets, or of a number of metal sheets, each pack (82) or metal sheet having two identical grooves (84) arranged for cooperation with wedge members (86) designed to join together packs (82) or metal sheets, and wherein the stator body comprises beams (88), each connected to a wedge member (86). The mounting device (80) also comprises a connector (90) arranged through the beam (88) and secured in the wedge member (86) in order to connect the beam (88) and wedge member (86) in such a manner as to permit sliding between the wedge member (86) and the beam (88) in the event of short-circuiting. The windings also consist of high-voltage cable (10).

Abstract: A plastic encapsulated optomodule is provided which includes a leadframe, an optoelectric component, an electric component, and an optical connection interface integrated in the capsule. The electric component is connected electrically to the leadframe. The electric component and the optoelectric component are mutually connected electrically and the optoelectric component and the integrated connection interface are connected together via at least one optical waveguide. The electric component is provided on a first part of the leadframe and electric contact surfaces (80) are provided on leads (5a and 5b) in the leadframe (1). The optoelectric component is provided on a second part of the leadframe and the optical connection interface arranged on an optodevice is connected to a third part of the leadframe. The optodevice is aligned by alignment elements provided on the leadframe and the leadframe includes alignment elements that conform with corresponding alignment elements on a plastic-encapsulation mold tool.

Abstract: To transfer mold a transfer molding compound on a substrate having discrete components (2) and solder balls (3) on one and the same side, the discrete components (2) having a height that is less than the diameter of the solder balls (3), the substrate is placed on one part (6) of an transfer molding tool with the components (2) and the solder balls (3) facing the other part (7). When the parts (6, 7) of the transfer molding tool are pressed together, that other part (7) is adapted to receive the components (2) and the solder balls (3) and comprises flat-bottomed cavities (8) for individually receiving a top portion of each solder ball (3) and for flattening the top portion of each solder ball (3).

Abstract: The present invention relates to a mold for simultaneously molding a plurality of ferrules onto a corresponding number of optical fibers. The mold preferably includes a runner plate, a first cavity plate, a second cavity plate, and a support plate, each of which is to be inserted between a movable top plate and a fixed bottom plate of a transfer molding machine. The plates to be inserted have a vertical inlet channel and primary and secondary runners for distributing molding compound. These runners lead to a plurality of first and second mutually coincidental mold cavities arranged in rows in the first and second cavity plates, respectively. In a preferred embodiment, each of the first and second mold cavities are made up of mutually coincidental, cylindrical coaxial parts and a larger coaxial, cylindrical bore formed in one or both cavity plates. The dividing plane between the first and second cavity plates coincides with the wider bore.
