Composition: A slip ring is typically made out of stationary graphite or metal contact (brush) that rubs on the outside diameter of a spinning metal ring. The electric current or signal is transmitted through the stationary brush to the metal ring forming the connection as the metal ring turns.
Slip rings are electromechanical devices used to transfer power from spinning to stationary structures. Slip rings are used to improve mechanical performance and simplify operations in a variety of electrical machines. A slip ring is composed of two parts: a metal ring and a brush contact.
The slip rings in the AC generator look like,
Therefore,
Slip rings come in a variety of styles.
The fabrication of these slip rings varies depending on the model.
The directions for manufacturing these slip rings are likewise varied.
Slip rings can be fashioned from a variety of materials.
