Patent number: 9484141Abstract: A three-phase stacked triangular transformer core is provided. The transformer has three legs and six yoke parts therebetween, wherein the legs include stacked laminations. In a cross-sectional plane perpendicular to a central transformer core axis, the stacked laminations are oriented in substantially radial direction, and each leg has two leg halves, wherein each leg half has a plurality of outer corners facing a corresponding leg half of a neighboring leg. For each of the leg halves the plurality of outer corners lie on a respective straight line within a lateral tolerance, and for each leg half the straight line defined by this leg half and the straight line defined by the corresponding leg half of the neighboring leg are parallel.Type: GrantFiled: August 8, 2013Date of Patent: November 1, 2016Assignee: ABB Schweiz AGInventors: Egil Stryken, Pawel Klys, John Wallumrod, Robert Platek, Tomasz Nowak, Abdolhamid Shoory

Publication number: 20160005536Abstract: A method for manufacturing a stacked triangular core transformer includes assembling a triangular core by positioning of two halves of one leg on an assembly stand in the horizontal position; securing the positioned halves; positioning an outer clamping beam underneath two leg halves at the one end of the leg halves; assembling a yoke segment at the one end of two halves of the core leg; and forming a first clamp of the frame. The method continues by forming a second clamp of the frame at the other end of the two halves of the core leg by repeating the above positioning, assembling and forming steps; tightening the clamps together by securing means; rotating a single core frame into vertical position and releasing securing bar of the assembly stand; assembling two additional single core frames by repeating the above steps; positioning the frames in abutting position, and tightening them together.Type: ApplicationFiled: February 7, 2014Publication date: January 7, 2016Inventors: TOMASZ NOWAK, ROBERT PLATEK, WOJCIECH WYSOCKI, PAWEL KLYS, WOJCIECH FABIJANOWSKI, EGIL STRYKEN, JOHN WALLUMROD, ABDOLHAMID SHOORY

Patent number: 7331636Abstract: A milling machine comprising a housing including a frame, a front wheel assembly supporting the housing, at least a first rear wheel assembly and a second rear wheel assembly supporting the housing, a milling drum mounted within the housing and extending below the housing, and an electric motor for providing power to at least one hydraulic system for operating milling machine functions. The first rear wheel assembly is ideally switchable between a first position and a second position to allow the milling machine to reach corners and other tight spaces in a building. The milling machine preferably further includes a dust collection system mounted within the housing to provide dust-free operation. The electric motor is also ideally mounted within the housing to provide a compact, dust-free and emissions-free milling machine for indoor use.Type: GrantFiled: October 7, 2004Date of Patent: February 19, 2008Assignee: Prep Engineering, Inc.Inventors: Donald D Troudt, John Easton, Robert A. Platek, Mark E. Vesely, Michael A. Paulick
