How A Slip Ring Works

A slip ring is a rotary coupling used to transfer electric current from a stationary unit to a rotating unit. This is accomplished by either:

  1. Holding the center core stationary while the brushes and housing rotate around it.
  2. Holding the brushes and housing stationary while the center core is allowed to rotate. 

A wide selection of circuitry is available with many combinations of amperage and voltage (AC or DC). The compact design is made possible by brushes stacked on alternating sides.
