Patent number: 10110079Abstract: The present disclosure broadly relates to apparatuses and methods for generating electric power. More particularly, the present disclosure relates to a self-excited electric generator. The self-excited electric generator may include auxiliary windings to provide a source of electricity to an associated generator control unit (GCU). The apparatuses and methods of the present invention may provide added benefits of reducing excitation requirements from the GCU. Thereby, the apparatuses and methods may reduce cost, weight, and size of an electric generator, and may increase reliability of associated systems.Type: GrantFiled: March 30, 2015Date of Patent: October 23, 2018Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Jens Gehrke, Simon Waddell, Wayne Pearson, Ming Xu, Cristian Anghel

Patent number: 9664232Abstract: A generator assembly may include a bearing liner and a bearing retainer configured to reduce vibration response in a bearing assembly under high frequency operation of a rotor. The bearing liner may be configured to provide a clearance between the bearing assembly and an adjacent housing/bearing liner to prevent high vibration output from the bearing assembly on for example, the rotor shaft. The bearing retainer may include a recess to accommodate axial movement of the bearing assembly in response to rotation of the rotor. In some embodiments, the bearing retainer may include a dampener to dampen contact of the bearing assembly with the retainer.Type: GrantFiled: July 18, 2013Date of Patent: May 30, 2017Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Balwinder Singh Birdi, Simon Waddell, William Scherzinger, David Windish, Robert Cisneroz

Patent number: 8210544Abstract: Apparatus for preventing incorrect installation of machinery components together includes a tab, pin and pin-receiving hole. The tab on the seal plate protrudes angularly from its periphery and laterally beyond it so as to prevent incorrect installation of two seal plates together in a faulty sealing relationship with machinery components by their tabs making interfering contact with one another producing a visible gap between the two seal plates. The pin is mounted on and protrudes axially from a surface of one machinery component facing the seal plate and prevents incorrect installation of the machinery components together in a faulty sealing relationship without the seal plate between them by the pin contacting the surface of the other machinery component and producing a gap between the machinery components. The hole extends through the seal plate to receive the pin within it when one seal plate is correctly installed between the machinery components.Type: GrantFiled: May 16, 2008Date of Patent: July 3, 2012Assignee: Honeywell International Inc.Inventors: Simon Waddell, Ed Down, William Scherzinger

Patent number: 8134268Abstract: A high speed aircraft generator may utilize a prefabricated crossover subassembly to interconnect field coils. The crossover may include two attachment leads interconnected with a section of braided wire. The braided wire may remain free of brazing filler metal after the crossover subassembly is brazed into position between field coils of the generator. Consequently, the crossover may remain flexible and may have reduced susceptibility to fatigue failure that may otherwise result from circumferential relative displacement of the field coils from one another during changes of rotational speed of the field coils.Type: GrantFiled: January 9, 2009Date of Patent: March 13, 2012Assignee: Honeywell International, Inc.Inventors: Simon Waddell, David Kane

Publication number: 20070090701Abstract: A rotor balancing system is provided that includes a rotor core, a plurality of core channels, a support wedge, a wedge channel, and balance masses. The rotor core includes an annular section, a first pole, and a second pole. The first and second poles each extend radially outwardly from the annular section and form an interpole region therebetween. The plurality of core channels are formed in the rotor core annular section and extend axially through the rotor core annular section. The support wedge is disposed in the interpole region. The wedge channel is formed in the support wedge and extends therethrough. One or more balance masses are selectively disposed in one or more of the core channels and the wedge channel, and each balance mass is disposed at a predetermined axial location to thereby correct rotor imbalance.Type: ApplicationFiled: October 25, 2005Publication date: April 26, 2007Inventors: Edward Down, David Stout, Simon Waddell

Patent number: 6903470Abstract: A rectifier hub and associated cooling method provide increased cooling efficiency for rotating rectifier diodes in a dry cavity generator. The rectifier hub has an inner and an outer circumferential surface and includes at least one pair of flow passages, and at least one flow channel. Each pair of flow passages extends between the hub inner and outer circumferential surfaces, and each flow channel is formed in the hub outer circumferential surface and couples the pair of flow passages in fluid communication with one another. This configuration allows a cooling medium to flow directly across the rectifier hub and cool the rectifier diodes mounted within drive cavities formed in the hub.Type: GrantFiled: August 22, 2002Date of Patent: June 7, 2005Assignee: Honeywell International, Inc.Inventors: Kieran Doherty, Shannon Rogers, William Scherzinger, David Stout, Simon Waddell, Ming Xu

Publication number: 20050023928Abstract: The coil end-turn segments of a generator exciter rotor are retained using an end-turn retention assembly that includes an inner band and an outer band. The inner band is located around at least a portion of each of the end-turn segments and has two ends. The outer peripheral surface of the inner band is tapered such that the thickness of the inner band varies between its ends. The outer band is located around the inner band and also has two ends. The inner peripheral surface of the outer band is tapered in a fashion that is reverse to that of the inner band outer surface, and such that the outer band thickness varies between its ends. By forming oppositely configured tapers in the inner and outer bands, the outer bands will remain in place and not migrate axially away from the lamination core during exciter rotor rotation.Type: ApplicationFiled: July 31, 2003Publication date: February 3, 2005Inventors: Kieran Doherty, William Scherzinger, David Stout, Simon Waddell, Shannon Rogers, James Ritter, Henry Pszczola, Shirley Pszczola
