Solid Freeform Fabrication by Selective Area Laser Deposition
Laser chemical vapor deposition is capable of selective area deposition of thin fums at high spatial resolution, and in the present work this advantage was used to perform solid freeform fabrication (SFF). The pyrolytic ...
Hydrodynamic bearing applications of micro-electro-mechanical systems
Microdynamical systems have been studied for a number of years, with concentration on sensors and, more recently, actuators. Only limited work has been completed on integrating microdynamical components into systems that ...
Pulsed Rotating Machine Power Supplies for Electric Combat Vehicles
As technology for hybrid-electric propulsion, electric weapons and defensive systems are developed for future electric combat vehicles, pulsed rotating electric machine technologies can be adapted and evolved to provide ...
Control System for Inside-Out Configuration Magnetic Bearings
The University of Texas Center for Electromechanics (UT-CEM) in association with the Texas A&M Vibration Control Lab (TAMU-VCL) has developed an active magnetic bearing control system for use in a 5 MW, 25 MJ, 20,000 RPM ...
Inside-Out Configuration Active Magnetic Bearing Actuators
The University of Texas Center for Electromechanics (UT-CEM) has designed active magnetic bearing actuators for use in a 5 MW flywheel alternator with a 700 lb (318 kg), 20,000 rpm rotor, under the sponsorship of the ...
Alternator Power Conditioning for Launchers
A high-energy pulse-discharge is needed to drive an electromagnetic (EM) or an electro-thermal-chemical (ETC) launcher. Various pulse power generators have been examined and used. Capacitor-based power supplies are convenient ...

Homopolar Welding for J-Lay Pipeline Construction
Homopolar Welding (HPW) is a high speed electric resistance forge welding process being developed for single shot girth welds proposed for the J-Lay pipelaying technique in deepwater. The homopolar welding technique uses ...
Advances in homopolar welding of API linepipe for deepwater applications
The University of Texas at Austin Center for Electromechanics is conducting a research program to study homopolar welding of line pipe for J-Lay applications. In 1995, the third year of the five year research program, ...
