Inexpensive Inertial Energy Storage Utilizing Homopolar Motor-Generators
The pulsed power demands of the current generation of controlled thermonuclear fusion experiments have prompted a great interest in reliable, low cost, pulsed power systems. The Energy Storage Group at the University of ...
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. ...
Methods for Producing the Plasma Initiation Pulse in Ohmic Heating Circuits in Tokamak Power Reactors: Resistive Dissipation, Transient Inductive Storage, and Transient Capacitive Storage
The plasma initiation phase occurring at the beginning of the operating cycle of a tokamak has the role of transforming a weakly ionized high resistance gas into a low resistance plasma type discharge. A plasma initiation ...
Circuit and Magnetic Analysis for a System of Faraday Rotator Coils Driven by a Two Spool, Four-Rotor Homopolar Generator
As part of a cost optimization study, a computer based circuit analysis is performed to determine the energy storage requirements a homopolar generator must meet to drive an inductive load of Faraday rotator coils, which ...
Design, Fabrication and Testing of a Fast Discharge Homopolar Machine (FDX)
The Fast Discharge Experiment (FDX) is a 0.36 MJ, 200 V homopolar machine designed to discharge in one millisecond. All components, including dual brush actuation systems, a room-temperature 2 x 106 A-t pulsed copper coil, ...
Electromagnetic Torques and Forces Due to Misalignment Effects and Eddy Currents in the Homopolar Generator Power Supply for the Texas Experimental Tokamak
Asymmetries in the applied magnetic field due to manufacturing tolerances and rotor-stator misalignments can cause significant forces and moments in a homopolar generator. Parasitic eddy-currents in the rotor, brushes and ...
