Patent number: 8739538Abstract: An apparatus includes an electric generator having a stator and a rotor. A first turbine wheel is coupled to a first end of the rotor to rotate at the same speed as the rotor. A second turbine wheel is coupled to a second end of the rotor opposite the first end, and configured to rotate at the same speed as the rotor. The first and second turbine wheels may rotate in response to expansion of a working fluid flowing from an inlet side to an outlet side of the turbine wheels.Type: GrantFiled: May 28, 2010Date of Patent: June 3, 2014Assignee: General Electric CompanyInventors: Scott R. Myers, David J. Huber

Publication number: 20130286591Abstract: A system for cooling components of a power generation system. The system may include a working fluid, 100% of which may be sent to a heat exchanger for cooling the components. During cooling, the working fluid may be retained in liquid form. All of the working fluid exiting the heat exchanger may be introduced to an evaporator which may transform the working fluid to a gas for use by an expander or other device to create motive power to run a generator. Upon exiting the expander, the gas may be condensed back to liquid form, 100% of which may be sent back to the heat exchanger to cool the components.Type: ApplicationFiled: April 30, 2012Publication date: October 31, 2013Applicant: General Electric CompanyInventors: Scott R. Myers, David Huber

Patent number: 8400005Abstract: A turbine wheel is rotatable in response to expansion of a working fluid flowing from near an inlet side towards an outlet side of the turbine wheel. The turbine wheel may receive the working fluid radially into the inlet side of the turbine wheel and output the working fluid axially from its outlet side. A generator has a stator and a rotor. The rotor may be coupled to the turbine wheel and may rotate at the same speed as the turbine wheel when the turbine wheel rotates. In certain instances, the generator is adjacent the inlet side of the turbine wheel.Type: GrantFiled: May 19, 2010Date of Patent: March 19, 2013Assignee: General Electric CompanyInventors: David J. Huber, Scott R. Myers

Patent number: 8384232Abstract: An apparatus includes an electric generator having a stator and a rotor. A turbine is coupled to an end of the rotor to rotate at the same speed as the rotor. The turbine may rotate in response to expansion of a working fluid flowing from an inlet side to an outlet side of the turbine. The apparatus also includes a housing assembly with an inwardly oriented shroud, which is located at close proximity to the turbine. The proximity of the shroud to the turbine establishes the pressure ratio of the turbine, allowing the system to operate without seals. Magnetic bearings and position sensors are used to maintain the distance between the shroud and the wheel. In certain implementations, the positioning of the turbine can be controlled to optimize machine performance.Type: GrantFiled: July 19, 2010Date of Patent: February 26, 2013Assignee: Calnetix Technologies, L.L.C.Inventors: Scott R. Myers, David J. Huber, Lawrence A. Hawkins

Patent number: 7638892Abstract: Some embodiments of a fluid expansion system include a turbine generator apparatus in which the driven member is arranged on the outlet side of the turbine wheel. In such circumstances, the fluid output from the turbine wheel can flow towards the driven member, for example, to provide heat dissipation to some components of the turbine generator apparatus (e.g., generator electronics or the like). This arrangement of the turbine wheel relative to the driven member also permits the use of bearing supports on both the input side and the outlet side of the turbine wheel.Type: GrantFiled: April 16, 2007Date of Patent: December 29, 2009Assignee: Calnetix, Inc.Inventor: Scott R.

Patent number: 5689175Abstract: A digital voltage regulator for an electrical power system including a permanent magnet generator (PMG), an exciter, and a main generator. A controller multiplies the frequency of the generator output voltage by a predetermined value to provide a sampling signal having the multiplied frequency and synchronized with the generator output voltage. The controller also provides a sawtooth voltage signal having a repetition rate equal to the frequency of the sampling signal and an incrementing rate determined by the system clock signal. The generator output voltage is sampled at the frequency of the sampling signal. When the difference between the sampled signal and a reference voltage is greater than the sawtooth voltage, the PMG voltage is switched to provide voltage for the exciter field winding.Type: GrantFiled: May 31, 1996Date of Patent: November 18, 1997Assignee: Sundstrand CorporationInventors: Michael J.
