A slip ring is a method of making an electrical connection through a rotating assembly.A slip ring consists of a conductive circle a shaft and insulated from it. Electrical connections from the rotating part of the system, such as the rotor of a generator, are made to the ring. Fixed contacts or brushes run in contact with the ring, transferring electrical power or signals to the exterior, static part of the system.This system is similar brushes to the commutator in many types of DC Motors.
