1. A slip ring assembly for transferring high currents of electrical power for high RPM operation between a stationary exterior environment and a rotating interior environment, comprising:
a. a non-rotating electrical power member, comprising:
i. a first electrically non-conductive spindle having a generally planar contacting surface;
ii. a first set of concentric channels formed in said first electrically non-conductive spindle planar contacting surface;
iii. a first set of concentric electrically conducting power transmission bands, wherein each power transmission band within said set fits within a separate channel of said first set of concentric channels;
iv. a set of first electrical wires with each member within said first wire set connected to one said electrically conducting power transmission bands and exiting from said non-rotating electrical power member;
b. a rotating electrical power member, comprising:
i. a second electrically non-conductive spindle having a generally planar contacting surface;
ii. a second series of concentric channels formed in said second electrically non-conductive spindle planar contacting surface;
iii. a second set of concentric electrically conducting power transmission bands, wherein each power transmission band within said set fits within a separate channel of said second set of concentric channels;
iv. a set of second electrical wires with each member within said second wire set connected to one said electrically conducting power transmission bands and exiting said rotating electrical power member; and
c. a housing that surrounds both said non-rotating electrical power member and said rotating electrical power member to align said first set of concentric electrically conducting power transmission bands and said second set of concentric electrically conducting power transmission bands to slide on one another over their said contacting surfaces during rotationally operation of the slip ring assembly.
