FDX--A Fast Discharge Homopolar Generator
During the winter of 1973 and spring of 1974 a study was undertaken by the Energy Storage Group* of The University of Texas at Austin to determine the fundamental limitations to the discharge times of homopolar generators. ...
Fundamental Limitations and Design Considerations for Compensated Pulsed Alternators
Since the beginning of a project intended to demonstrate the feasibility of using a compensated pulsed alternator (compulsator) as a power supply for NOVA and other solid state laser systems, a great deal of interest has ...
Homopolar Motor-Generator for Inexpensive Inertial Energy Storage
During the last six months, the Energy Storage Group has completed the assembly of the five megajoule homopolar motorgenerator and begun an extensive testing and evaluation program on the unit. The study of the fundamental ...
Possible Errors in Measurement of Air-Gap Torque Pulsations of Induction Motors
Measurements based on the accurately obtained air gap flux data using either the search-coil or the Hall-effect approach are not error proof. This is because even the unbalanced leakage effects can be reduced to a minimal ...
Pulsed Power Requirements for EM Launchers
Both linear (railgun) and coaxial (mass driver, etc.) electromagnetic launchers (EMLs) are treated as time-varying impedances to determine the relationships between acceleration force, payload velocity, and power supply ...
Fundamental limitations and topological considerations for fast discharge homopolar machines
Fusion research experiments require high energy short duration pulses. A homopolar machine, as an inertial energy storage system, offers an attractive source of energy meeting these requirements. The Energy Storage Group ...
Fabrication of a Compact Storage Inductor for Railguns
A liquid nitrogen-cooled, coaxial, energy storage inductor has been designed and built to be used in conjunction with a compact homopolar generator to form a high-energy-density power supply for use with electro-magnetic ...
Five-Megajoule Homopolar Upgrade
The five-megajoule homopolar generator (5-MJ HPG) designed and built in 1974 by the Center for Electromechanics at the University of Texas at Austin (CEM-UT) was the result of an engineering feasibility study that examined ...
