Patent number: 7461443Abstract: An inner sleeve, having threads on each end, is formed on a motor or generator rotor. A pair of stub shafts are threadably attached to the inner sleeve at each end and a magnet is placed in between. The stub shafts are turned on the inner sleeve to bring them together, thereby creating an axial compressive force on the magnet. By keeping the magnet in a compressive state at all times, cracking of the magnet is prevented, thus keeping the rotor stable during use of the motor or generator. An outer sleeve is shrunk-fit around the magnet and stub shafts to provide a further radial force on the rotor. The magnet assembly of the present invention also enlarges the required radial shrink-fit tolerance of the outer sleeve on the magnet, thereby reducing costs conventionally required to match the outer sleeve to the magnet within close tolerances.Type: GrantFiled: April 27, 2006Date of Patent: December 9, 2008Assignee: Honeywell International, Inc.Inventors: Sam Shiao, Robert P. Chen

Patent number: 7462098Abstract: An aircraft cabin pressure control system implements control logic that significantly reduces potentially uncomfortable pressure bumps that can occur during aircraft take-off rotation both with and without cabin pressuring fluid flowing into the aircraft cabin. The control logic implemented by the cabin pressure control system, among other things, determines whether the cabin pressurizing fluid is flowing into the aircraft cabin. If the cabin pressurizing fluid is flowing into the aircraft cabin, aircraft cabin altitude is controlled to at least a first predetermined minimum altitude value below the take-off altitude. If the cabin pressurizing fluid is not flowing into the aircraft cabin, aircraft cabin altitude is controlled to at least a second predetermined minimum altitude value above the take-off altitude.Type: GrantFiled: March 16, 2005Date of Patent: December 9, 2008Assignee: Honeywell International, Inc.Inventors: Timothy R.

Patent number: 7463473Abstract: A field discharge circuit may rapidly reduce the field current of a generator, thereby avoiding an overvoltage condition. The field discharge circuit of the present invention may use another storage device, such as a capacitor, to quickly transfer the field current energy thereto and then slowly dissipate the transferred energy after the event (such as removal of a load) has passed. By transferring this energy to a storage device and subsequently slowly discharging this energy through a resistor, electromagnetic interference caused by a conventional resistive discharge can be reduced.Type: GrantFiled: April 18, 2007Date of Patent: December 9, 2008Assignee: Honeywell International, Inc.Inventors: Mohamed A. Eldery, Robert D. Paton

Patent number: 7459889Abstract: Conventional electric power generation system employ a solid state electronically controlled IM that may be capable of self-start motoring and power generation, but, when the DC bus voltage collapses upon a failure, an additional external source of DC voltage is not available for IM excitation. The present invention provides an internal bus that does not collapse when the main DC bus is shorted. This internal or auxiliary bus may be used to excite the IM to provide generation function. The power generation systems of the present invention may play a significant role in the modern aerospace and military industries.Type: GrantFiled: January 9, 2007Date of Patent: December 2, 2008Assignee: Honeywell International, Inc.Inventors: Evgeni Ganev, Leroy A.

Patent number: 7454254Abstract: A cabin pressure control system and method that reduces or inhibits gear train backlash and the concomitant cabin pressure oscillations associated therewith. The cabin pressure control system includes a variable proportional-integral (PI) controller that implements a proportional function with a variable gain term and an integrator function with variable saturation limit. The proportional function gain term is increased, and the integrator saturation limits are decreased, at relatively low cabin error rate magnitudes. Increasing the proportional function gain term at relatively low cabin error rate magnitudes offsets potential backlash effects from the gear train. Decreasing the integrator saturation limits at relatively low cabin rate error magnitudes reduces potentially excessive integrator wind-up levels, which reduces the likelihood of producing limit-cycling and the potential for cabin pressure oscillations.Type: GrantFiled: August 30, 2005Date of Patent: November 18, 2008Assignee: Honeywell International, Inc.Inventor: Gerard L. McCoy
