Ultimate Guide to Slip Rings for Unmanned Aerial Vehicles

This detailed guide is intended to provide you with an in-depth understanding of industrial slip rings and their various applications.

We put together this definitive guide. You’ll not only learn about the different types of slip rings and their practical uses within the engineering industry, but also assembly systems and market analysis forecasted for the next five years.

Are you a fan of using unmanned aerial vehicles (UAVs) like drones and Hybrid VTOLs? Perhaps you’re just an industry enthusiast looking to know more about these UAVs and their various components.

Either way, you already know that these aerial machines cannot function if all their components are not in perfect working conditions. Slip rings play a pivotal role in the proper functioning of your UAV, so you definitely want to get a full grasp of what they are about and how to make sure they remain functional.

Let’s begin then. Shall we?

Chapter 1 - Understanding Slip RIngs and Their Practical Function

In simplest terms, a slip ring is an electromechanical piece of hardware that facilitates the transmission of electrical signals and power to a rotating structure. Basically, it is that crucial component that allows the rotor of unmanned aerial vehicles and any other electromechanical system that depends on steady rotation to function.

It is usually installed in the rotation center of the mechanical equipment, which is composed of two main parts -- the rotor and stationary components.

How does a slip ring work?

Slip rings can simplify system operation and improve mechanical performance by connecting the statutory body with the rotary structure and rotating at a continuous 360-degrees.

A typical slip ring consists of a stationary graphite or brush (metal contact), which then makes contact with the outside bore of a rotating round metal band. As this ring rotates, the slip ring conducts the electric current or signal through the stationary brush to the metal ring, making the connection.

Now as long as this slip ring is attached to an infinitely rotating equipment, it can provide power to the rotating body continuously. You’ll find that most slip rings are contained within sturdy cassements to protect them from moisture, dirt, and other forms of debris that can lead to malfunction down the line.

Chapter 2 - Different Types of UAV Slip Rings and Their Unique Features

You already know that slip rings help to transmit the needed signal and current from the stator to the rotor of an electromechanical system. But with so many different types of unmanned aerial vehicles on the market today, you’re probably wondering:

  • how many types and models of slip rings are in use today?

  • Are there any major differences between them?

Well there are several types, some of which include:

Miniature Slip Rings

These are small electrical device (OD<12.5mm) can transmit power and signal from static to rotational components. Their minute sizes make them the ideal choice for video transmission and other miniature rotating systems of transmitting low controlling signals.

This slip ring also produces less torque, low noise, and is less prone to damage.

Moog Slip Ring

Featuring an RPM (revolutions per minute) of 600 - 20000, the moog slip ring is mainly used in the aerospace and the defense fields for regions that have high mountains or rugged environments. Due to its unique composition, this type of slip ring is custom constructed to fit the needed requirements.

It eliminates the dangling wires from the moving connectors, which in turn makes it the ideal choice for laser augmentations, different forms of fire control systems, and high volumes of bandwidth data signals.

Ethernet Slip Ring

Also known as the RJ 45 slip ring, this type of slip ring is designed for high frequencies of up to 250 MHz. It can transmit varying levels of high ethernet signals and has a lower low insertion loss compared to other slip rings.

More importantly, it boasts a unique combination power, which allows it to combine seamlessly with other types of slip ring, like the hydraulic or pneumatic slip ring.

Chapter 3 - Slip Ring Maintenance

Regular maintenance is crucial to improving the performance of a slip ring, as well as increasing its life expectancy. The maintenance information is usually provided by the slip ring manufacturer, but the general rule is to perform an annual check-up and then doing some detailed maintenance every 3-5 years.

This is because long-term rotations lead to increased wear and tear of its components, especially the brushes and rings. Here are some tips to consider for slip ring maintenance:

  • Rotating shafts with high rotational velocity leads to more friction and rampant heat that wears down the rings over time. To avoid this, you should select a slip ring with less thermal affinity so it can withstand the constant heat from the continuous long-term rotations.

  • Some slip ring damage can result from too much exposure to dust and moisture, so if you can, make sure to cover it with rubber or wax coating.

Alternatively, if you can disassemble the UAV easily, then simply take out the slip ring and clean it every now and then.

  • If you use your unmanned aerial vehicles a lot, then consider replacing the brushes from time to time to ensure maximum efficiency of the machine and the rings.

Chapter 4 - Avoid These Four Mistakes When Buying Slip Rings

  • Settling for cheap prices -- The problem with buying a cheap slip ring is that you get what you pay for. Low price often means lower quality, so you end up having to replace it quickly.

  • Not going for Brand Items -- With so many types and variations of slip rings on the market today, the important thing is to choose a reputable slip ring manufacturer. This way, you will not only get quality products, but also benefit from good customer service.

  • Not choosing the right range -- When buying a slip ring, you should consult the environmental index control, so you can see the best range for it and the compatible machines. Failure to do so means you may end up buying a large and costly operating range, which will only be a waste of resources.

  • Poor Installation -- Like with any other specialized electromechanical component, slip rings should only be installed and operated by a professional technician so avoid technical errors. Sometimes, the slip ring manufacturer will have a list of approved installers who are qualified to get the job done for you.

Chapter 5 - Slip Ring Market Analysis, Growth Rate, and Forecast For the Next 5 Years

Recently, MF Journalism, a global news and market research agency, published an industry report highlighting the current trends and new product developments in the global slip rings market. By understanding the market better, all major industry players can better explore upcoming international opportunities.

The report also provided a comprehensive breakdown of the slips rings market in terms of market growth, key trends and segmentation analysis of.
