Slip Ring Commutator Function

You may have noticed that the design and function of a slip ring sounds very similar to that of a commutator.

Slip ring commutator function.

Slip ring commutator can recover mechanical action facilitate system function and eliminate damage prone wires that are attached to variable joints. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. But the function of both of these arrangements is different. The slip ring commutator construction is consists of immobile graphite otherwise brush which is known as metal contact which wipes on the exterior diameter of a revolving metal ring.

In the below table we summarized differences between the slip ring and commutator. A commutator or slip ring surface can be reconditioned in any one of seven ways although other methods have been used in emergencies. The recognised and approved techniques are listed below in order of preference. The slip ring and split ring both are made of copper but their design differs from each other.

Turning with a tungsten carbide tipped tool 3. It can improve mechanical performance simplify system operation and eliminate damage prone wires dangling from movable joints. Physically a slip ring is a continuous ring whereas a commutator is segmented. The dc supply that we generate after rectification of the alternator output static excitation system is considered here is stationary but the rotor to which it is to be fed.

While there are similarities between the two there are critical distinctions between slip rings and commutators. When the metal ring twists the flow of electric current otherwise signal is performed through the immobile brush toward the metal ring for making the connection. Grinding with a rotating wheel 4. Slip ring or commutator.

Slip rings are used as a means of providing dc excitation to the rotor of the alternator. Slip ring commutator construction. If you need a custom slip ring self contained slip ring large slip ring or even sllip ring mountaing brackets we can do it. In case of ac motor the input current through the brush passes to slip ring which connects to the coil of the ac motor thus the current flows from the static to the movable part.

Both the slip ring and commutator made of conductive material. From complex electrical slip rings to through bore slip rings. The slip ring is a closed circular ring having brushes on their outer surface. In some excitation schemes the need of a slip ring arrangement may however be eliminated as with the brushless excitation system.

The slip ring and commutator both are used to maintain a connection between the rotating system and the electrical system. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.
