APPARATUS AND METHOD FOR AXIALLY SPACING CONDUCTIVE RINGS OF A SLIP RING ASSEMBLY

摘要

An apparatus for determining axial spacing between conductive rings of a slip ring assembly includes a signal generator that generates an incident signal, a plurality of conductive rings axially spaced along a shaft where the plurality of conductive rings includes a first conductive ring and a second conductive ring that are axially spaced at a first axial distance. The shaft and the plurality of conductive rings are submerged in a bath of a liquid or encased in an epoxy. A first twisted wire pair is electronically coupled at to the signal generator and to inputs of the first and second conductive rings. A second twisted wire pair is electronically coupled at one end to outputs of the first and second conductive rings. A method for determining axial spacing between conductive rings of a slip ring assembly is also disclosed.
