Slip Ring Commutator Function

The slip ring is a closed circular ring having brushes on their outer surface.

Slip ring commutator function.

Slip ring commutator construction. Grinding with a rotating wheel 4. The slip ring and split ring both are made of copper but their design differs from each other. It can improve mechanical performance simplify system operation and eliminate damage prone wires dangling from movable joints.

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. Turning with a tungsten carbide tipped tool 3. 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. Both the slip ring and commutator made of conductive material.

In the below table we summarized differences between the slip ring and commutator. The slip ring commutator consists of an immobile brush which washes the exterior diameter of a revolving metal ring and it is known as a metal contact. 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. You may have noticed that the design and function of a slip ring sounds very similar to that of a commutator.

From complex electrical slip rings to through bore slip rings. Physically a slip ring is a continuous ring whereas a commutator is segmented. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. The recognised and approved techniques are listed below in order of preference.

Slip rings are used as a means of providing dc excitation to the rotor of the alternator. The slip ring and commutator both are used to maintain a connection between the rotating system and the electrical system. Turning with a diamond tipped tool 2. If you need a custom slip ring self contained slip ring large slip ring or even sllip ring mountaing brackets we can do it.

But the function of both of these arrangements is different. A commutator or slip ring surface can be reconditioned in any one of seven ways although other methods have been used in emergencies. Slip ring commutator can recover mechanical action facilitate system function and eliminate damage prone wires that are attached to variable joints. While there are similarities between the two there are critical distinctions between slip rings and commutators.

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. In some excitation schemes the need of a slip ring arrangement may however be eliminated as with the brushless excitation system.
