A slip ring is a way to make an electrical connection through rotating assemblies. The slip rings are common to be found in the electrical generators for electrical systems and alternators as well as packaging machinery, cable reels, and wind turbines. The function of slip rings in an electric generator is that one of the two rings is linked with one end of the winding of the armature and the other to the other end of the winding of the armature. Electricity or signal is continuously transmitted by a slip ring connector from a stationary source to a rotating destination or vice versa.
Moreover, the function of slip rings in an electric generator is that the hollow rings are linked to the ends of the armature coil and it helps to rotate the coil. They also provide electrical contact via the brushes.
