Original poster: "by way of Terry Fritz <twftesla-at-uswest-dot-net>" <CTCDW-at-aol-dot-com> Jason, Not having seen the setup you are describing, my second thought, after the first one, which was about the safety aspects of such a "rotor" is that if you are going to use the AL as the conductor between the stationary electrodes, how will you insulate it from the motor shaft??
