Slip Rings

A slip ring is an electromechanical device that enables the transfer of power and electrical signals between a stationary part and a rotating part. In simple terms, it allows continuous rotation while maintaining an uninterrupted electrical connection.

How Slip Rings Work

Slip rings consist of:

• Rotating rings (conductive tracks, usually copper-based)
• Stationary brushes (graphite, metal, or composite contacts)

As the shaft rotates, the brushes maintain sliding contact with the rings, enabling current or signals to pass seamlessly. This makes slip rings essential in systems where continuous 360° rotation is required without tangling wires.
