Slip rings, also known as rotary electrical connectors or commutator rings, are electromechanical devices that allow for the transmission of electrical power and/or data signals from a stationary source to a rotating component. They are essential in applications where continuous rotation is required while maintaining electrical connection. A typical slip ring assembly consists of a series of conductive rings, each insulated from the others and mounted on a rotating shaft. Stationary electrical contacts, often in the form of brushes made of carbon or metal alloys, press against these rings, completing the electrical circuit.

The primary function of a slip ring is to prevent wires from twisting and breaking as a component rotates. This is crucial for the longevity and reliability of machinery. Common applications include wind turbines, where they transmit power from the generator to the grid and control signals to the rotor blades, and robotics, where they enable continuous movement of robotic arms while supplying power and data. Other uses are found in industrial automation, medical equipment, defense systems, and in the entertainment industry for rotating stage lighting.

Slip rings can be designed to handle various types of signals, from high-power electrical currents to low-level data transmissions like Ethernet or USB. The choice of materials for the rings and brushes is critical and depends on factors such as the required current capacity, desired lifespan, operating environment, and the speed of rotation. Advancements in slip ring technology have led to smaller, more durable, and more efficient designs capable of handling increasingly complex electrical and data requirements.
