What Are Slip Rings

What Are Its Components and How Do They Function?

A slip ring, at its core, has a fairly straightforward structure. It is fundamentally composed of two primary components: a conductor ring (also known as a rotor) and a brush. The conductor ring is the rotating part and is often made of conductive metals like copper, brass, or silver depending on the application. Mounted on a rotating assembly, it rotates in conjunction with the machinery it’s integrated into. The brush, by contrast, remains stationary and is typically made of carbon or metal. This brush is precisely placed so it maintains constant contact with the rotating ring as it turns, allowing electrical signals or power to be transferred through the brush to the ring and then into the rotating device. The play of these components ensures continuous, uninterrupted transmission of power or signals.
