A slip ring is an electromechanical device that allows the transmission of electrical signals and power between stationary and rotating parts of a machine. It consists of a conductive ring and brushes that maintain contact with the ring, enabling continuous rotation without tangling wires. Slip rings are commonly used in applications like wind turbines, robotics, and cameras. These devices are essential in systems where rotation is required, such as in electric motors and turbines. By providing a reliable connection, slip rings help improve the efficiency and functionality of various machinery, ensuring smooth operation and reducing wear on cables.
