Collector Rings

How Do Dynapac Rotators Rotate Without Twisting or Tangling Any Wires?

The Answer: Collector Rings and Brush Assemblies

Collector Rings and Brush Assemblies are housings made from thermosetting plastics (plastic that starts out as a soft solid or liquid and is irreversibly cured and hardened by heat) that serve as insulators for metal components called Slip Rings (found on Collector Rings) and Brushes (found on Brush Assemblies). These Slip Rings and Brushes are just as conductive as regular copper wire but lack any parts that may twist or tangle.

Collector Rings are secured to the center shaft of the unit so when the unit is powered on, they will spin along with the turntable. Brush Assemblies, however, are mounted with a bracket to the frame of the unit so they remain stationary when the unit is power on. Collector Rings and Brush Assemblies are lined up inside the unit so the Brushes and Slip Rings can make contact with each other.

Power flows from a stationary source, like an outlet, into the unit where it will pass through the Brushes to the Slip Rings and then on to power lights, audio, etc..
