Abstract: A three-phase dynamoelectrical permanently excited synchronous machine includes a stator with teeth which point to a rotor, wherein twelve slots are formed between the teeth. The slots have coil sides of coils of a winding system in such a manner that two coil sides of different coils are situated in each slot. The rotor has a cylindrical support structure which is provided with permanent magnets defined by an inner radius which corresponds to a radius of the support structure, and by an outer radius which is smaller than their inner radius. The permanent magnets are formed with ten magnet poles when viewed in a circumferential direction.

Abstract: In a three-phase permanent-magnet synchronous machine, a pole gap and a skew of permanent magnets on the rotor are designed such that oscillating torques which are caused by the fifth and seventh harmonics of the stator field and of the rotor field are mutually reduced. In particular, the skew can be chosen as a function of the pole gap, such that the majority of the respective oscillating torques is neutralized. This results in minimal torque ripple.

Abstract: A wire section of a machine for making a fiber web, with two continuous wires forming together a twin-wire zone. A dewatering element is pressable on the inside of the wire with at least one surface. The dewatering element features in the direction of travel of the fiber suspension, in interaction with the wires, two dewatering zones. The first dewatering zone is defined by an essentially flat surface, while a second dewatering zone is defined by a surface curving about an axis of curvature in the direction of travel of the fiber suspension. Coordinated with the dewatering element are at least two support axes on which support elements are arranged. Coordinated with the dewatering element is a pivot axis. The pivot axis is stationary as regards the tilting operation, and extends parallel to the separation plane between the first and second dewatering zones and parallel to the wire. The pivot axis is arranged in the area of the axis of curvature.

Abstract: A method for transferring a continuously arriving web, specifically a paper or cardboard web, from a finished product roll to a new core rotating at the speed of web travel. The new core bears in the direction of web travel and before the finished product roll on a drum around which loops the web. The web is cut longitudinally, prior to running on the drum, for forming a transfer strip. Before reaching the new core, the transfer strip is severed from the advancing web and passed onto the new core. The web is subsequently cut across its entire width, wherein this cut originates from the longitudinal cut.A drum winder for accomplishing the method wherein the severing device for the transfer strip is arranged before the intake gap between the drum and the new core. A high-pressure water jet is used for severing the transfer strip from the web.

Abstract: In order to connect an angle measuring device to a brushless direct-current motor, a coupling is used, the coupling halves (10, 28) of which are each attached to the rotor (46) of the motor and/or the rotor (42) of the angle measuring device. Instead of using a coupling that is rotationally symmetrical at arbitrary angular positions as in the prior art, a coupling is used in which the coupling halves (10, 28) can be connected to one another only in a finite number of relative angular positions. An adjustment must be made before the coupling halves (10, 28) are attached to the respective rotors (46, 52). This allows all subsequent adjustment to be omitted, for example, even for maintenance work.

Abstract: A paper machine forming section with two wire forming units. One of the two forming units is a twin wire web forming unit having a headbox, two wire loops arranged in sandwich-like manner and a drainage element for each of the wire loops. The first web-forming unit has a first section including a curved suction drainage element or roll in the first lower wire loop; a second section with opposing drainage ledges, wherein the drainage ledges are stationary on the upper side and the drainage ledges are developed resiliently pressable on the bottom side; the drainage ledges of the upper and lower sides are arranged staggered with respect to each other in the direction of travel of the wire, and at least the ledges of the upper side are developed with suction; a third section which has at least one suction wire separating element on one side. The second web-forming unit is a hybrid former with a single wire. The guide rolls for the second wire of the first former and for the wire of the second former guide them on a joint wire path where the multilayer web is transferred to the wire of the second former. There is a headbox associated with the wire of the second former. A respective backwater circuit collects water and materials drained from each of the forming units and returns them to the respective headboxes.

Abstract: A twin-wire section with a first and a second endless wire, for forming a fiber material web of a fiber suspension, notably for forming a ply of a multiply paper or cardboard web, the ply being merged on a third wire with a further ply. In the twin-wire zone formed by the first and second wires, a dewatering box (touching the one wire) that features rigid slats is contained in the loop of the one wire, while in the loop of the other wire there are contained several backing slats which can be pushed flexibly on the other wire, while a loop of one of the two wires contains a forming roll which together with said wire forms a looping zone. The forming roll has a smooth, continuous roll shell. The wire which in the looping zone is outside separates from the web and the inner wire at a distance before the end of the looping zone.
