Patent number: 7152306Abstract: A method for installing a stator winding in a stator core. A winding turn is formed by drawing a cable portion from a cable reel and inserting it into two winding slots.

Patent number: 7141908Abstract: In a rotating electrical machine a stator winding is formed of flexible cables inserted in an open stator in the stator core. The stator slots extend from a radially outermost yoke part of the stator core radially inwards towards the rotor, the stator slots being separated by teeth. The stator slots are shaped as double slots with shoulders arranged in the slot walls such that each cable in the winding is secured between the previous cable in the stator slot and, seen from the slot opening, the next shoulder situated outside that particular cable. In a method for manufacturing such a winding the first cable is inserted through the opening of the stator slot and pressed firmly into a cable slot arranged at the bottom of the stator slot and designed to retain the cable when it has been pressed in.Type: GrantFiled: March 1, 2001Date of Patent: November 28, 2006Assignee: ABB ABInventors: Goran Holmstrom, Lars Hedendahl, Lars Walfridsson

Patent number: 7143149Abstract: A communication system that enables an operator to remotely query and control the process sections in an industrial plant by exchanging data with a central computer that controls the process sections. The operator communicates with the process sections through a mobile wireless device remotely connected with one of the multiple wireless access points on a data network. This data network is, in turn, connected to the central computer that controls these process sections. The central computer stores the location of the process sections and the operator profiles. When requested, it collates and processes this data and presents it to the operator. Further, if the need arises, the central computer tracks and interacts with the operator.Type: GrantFiled: September 21, 2001Date of Patent: November 28, 2006Assignee: ABB ABInventors: Pierre Öberg, Jan-Erik Frey

Patent number: 7117080Abstract: A method and apparatus for accurately determining TDC in a cylinder of an internal combustion engine. Gas pressure is measured in the cylinder relative to crank angle, giving rise to a curve of gas pressure with crank angle. An offset is found by first computing the angular position of an inflexion point of the compression pressure curve measured as a function of the crank angle, and then computing the offset as the difference between the angular position of a piston in the cylinder and a theoretical value for said angular position of the piston dependent on a known or measured flywheel angle. The value of TDC corrected by the offset is then used to calculate a value of work output such as the Indicated Mean Effective Pressure (IMEP) which may be used for diagnostic and/or control purposes.Type: GrantFiled: June 6, 2002Date of Patent: October 3, 2006Assignee: ABB ABInventor: Jarl R.
