High Current and High Current Density Pulse Tests of Brushes and Collectors for Homopolar Energy Stores
The incentive exists to use high collector current densities in pulsed duty homopolar generators, the current densities of interest being in the range of 15--45 MA/m2. Tests have been conducted in which current pulses of ...
Physical Scale Modeling to Verify Energy Storage Inductor Parameters
In the pulse charging and discharging of energy storage inductors, the influence of I2R heating, magnetic diffusion skin depth, and eddy current losses must be evaluated. These effects are not easily treated analytically. ...
High Speed, High Current, Copper-Finger Brushes for Pulsed Homopolar Generator Service
ln continuing research into higher energy density, higher current rated pulsed homopolar generators (HPG's), solid copper fingers are explored as sliding electrical contacts to slip speeds of 300 m/s and collector area ...
