ABSTRACT:
A slip ring assembly having a rotatable chamber including a shaft rotatably mounted therein. A plurality of slip rings are provided within a ring section of the rotatable chamber and are mounted to the shaft for rotation therewith. The plurality of slip rings for a group of preselected pairs of slip rings. An electrical conductor is connected to each slip ring with each electrical conductor being twisted to at least one adjacent electrical conductor through a central core in the shaft to thereby cancel alternating current due to self-generated voltages. The slip ring assembly also includes a brush assembly having at least one brush support associated with each slip ring with each brush support having brushes extending therefrom in contact with its corresponding slip ring at at least two brush contacts. The brush contacts for each slip are orientated approximately 180 degrees apart. Furthermore, brush contacts for each preselected pair of adjacent slip rings are orientated at an offset of approximately 90 degrees.
