Slip ring wikipedia-Slip ring motor - Wikipedia

A wound-rotor motor is a type of induction motor where the rotor windings are connected through slip rings to external resistance. Wound-rotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the motor accelerates, the resistance can be decreased. Compared to a squirrel-cage rotor , the rotor of the slip ring motor has more winding turns; the induced voltage is then higher, and the current lower, than for a squirrel-cage rotor. During the start-up a typical rotor has 3 poles connected to the slip ring. Each pole is wired in series with a variable power resistor.

Since poles and coils are equally spaced and the locations of the poles match to the locations of the coils, the magnetic lines of force are cut at the same amount at any degree of the rotor. The next-generation in Slip ring wikipedia rings, Roll-Rings replace the sliding contact of slip rings with rolling contact for electrical transfer that has much lower contact resistance. Either the brushes or the rings are stationary and the other component rotates. Cordless power tools typically use brushed DC motors, which I guess also use brushes and commutators, but, for some reason, the brushes found in universal motors made to run on mains power, those brushes seem to be bigger and sturdier, than the ones found in Slip ring wikipedia DC motors.

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.

Also called rotary electrical interfaces , rotating electrical connectors , collectors , swivels , or electrical rotary joints , these rings are commonly found in slip ring motors , electrical generators for alternating current AC systems and alternators and in packaging machinery, cable reels, and wind turbines.

They can be used on any rotating object to transfer power, control circuits, or analog or digital signals including data such as those found on aerodrome beacons , rotating tanks , power shovels , radio telescopes , telemetry systems, heliostats or ferris wheels.

A slip ring in electrical engineering terms is a method of making an electrical connection through a rotating assembly. Formally, it is an electric transmission device that allows energy flow between two electrical rotating parts, such as in a motor.

Typically, a slip ring consists of a stationary graphite or metal contact brush which rubs on the outside diameter of a rotating metal ring. As the metal ring turns, the electric current or signal is conducted through the stationary brush to the metal ring making the connection.

Either the brushes or the rings are stationary and the other component rotates. Some other names used for slip ring are collector ring, rotary electrical contact and electrical slip ring. Some people also use the term commutator ; however, commutators are somewhat different and are specialized for use on DC motors and generators.

While commutators are segmented, slip rings are continuous, and the terms are not interchangeable. Rotary transformers are often used instead of slip rings in high-speed or low-friction environments.

A slip ring can be used within a rotary union to function concurrently with the device, commonly referred to as a rotary joint. Slip rings do the same for electrical power and signal that rotary unions do for fluid media. They are often integrated into rotary unions to send power and data to and from rotating machinery in conjunction with the media that the rotary union provides.

Slip rings are made in various types and sizes; one device made for theatrical stage lighting, for example, had conductors. Mercury -wetted slip rings, noted for their low resistance and stable connection use a different principle which replaces the sliding brush contact with a pool of liquid metal molecularly bonded to the contacts [6]. During rotation the liquid metal maintains the electrical connection between the stationary and rotating contacts.

However, the use of mercury poses safety concerns, as it is a toxic substance. If a slip ring application involves food manufacturing or processing, pharmaceutical equipment, or any other use where contamination could be a serious threat, the choice should be precious metal contacts. Leakage of the mercury and the resultant contamination could be extremely serious. A pancake slip ring [8] has the conductors arranged on a flat disc as concentric rings centered on the rotating shaft.

This configuration has greater weight and volume for the same circuits, greater capacitance and crosstalk, greater brush wear and more readily collects wear debris on its vertical axis. However, a pancake offers reduced axial length for the number of circuits, and so may be appropriate in some applications.

Wireless slip rings do not rely on the typical friction based metal and carbon brush contact methods that have been employed by slip rings since their invention, such as those explored above.

Instead, they transfer both power and data wirelessly via a magnetic field , which is created by the coils that are placed in the rotating receiver, and the stationary transmitter. However, the amount of power that can be transmitted between coils is limited; typically a traditional contact-type slip ring can transmit orders of magnitude more power in the same volume.

I am looking to build a rotating electrical connector, better known in the electrical world as a slip ring. Hi bill I read your question there are a few way to do this. Knowing the voltage and amperage would help to offer a solution also dose it rotate more than deg and if so how fast. Cutting sections of matching width from a copper tube would serve as the slip ring side of things. They would of course have to be insulated if slipped over a metal shaft, but that is easily done using a combination of resin and insulating paper used for motor windings.

It also has a page for, "Brush electric " and "Commutator electric ", which are related concepts. I think automotive alternators have slip rings, although it has been a while since I took apart an alternator. Actually these days, I do not have to actually take one apart to find out what is inside, since there is an abundance of pictures and diagrams available, just for the trouble of an image search for the same.

Universal motors contain brushes and commutators, which are similar, and discarded universal motors are very easy to find. Examples include, blenders, vacuum cleaners, electric drills, but not the cordless kind.

Cordless power tools typically use brushed DC motors, which I guess also use brushes and commutators, but, for some reason, the brushes found in universal motors made to run on mains power, those brushes seem to be bigger and sturdier, than the ones found in brushed DC motors. Anyway, I was thinking that maybe some existing artifact, preferably one that is cheap, or free as discarded junk, could serve as the source for your slip rings.

Unless all the existing things are totally the wrong shape for what you want to build, then I guess these could serve as inspiration only, for the thing you have to build from scratch. If the application is not something where the rotation is not continuous or frequent, one quick and dirty solution would be something like an audio plug and jack.

Some of these contain as many as four separate contacts. If the application has the rotating device on a motor shaft or other situation where it would be spinning fast or expected to spin many cycles over its life, then the connector idea I described would be inadequate.
