Why slip ring is applied?

In electrical design, when the mechanical part is under 360 degrees unrestrained continuous rotation and the wires should be connected to the rotating part, then the electrical engineer needs an electrical rotary joint to avoid wires twisting, generally, we called this electrical rotary joint a slip ring.

Slip ring is also called a rotary electrical interface, commutator,collector,swiver, connector or an electrical rotary joint, it can be used in any electro-mechanical system which requires unrestrained continuous rotation while transmitting power and/or data from a stationary to a rotating structure.

Slip ring is made of brushes, conductive rings, insulation materials,binding materials,support frame, precisious bearings and housing etc. The brushes are made of precious metal with multi contact points to the ring.
The slip rings are widely used in security system, automative system, inspection equipments, wind turbines, detecting equipments and medical equipments etc.
