DIY Slip Ring: The Step by Step Guide
Slip rings are one of the most used electromechanical devices in industries. You can observe in electrical generators, wind turbines, gyroscopes, telescopes, mining, beacons, and other motor devices. These devices help to rotate components freely, just like a ball bearing.
Due to the multiple applications, there are available in different types based on their specifications. Sometimes we need to make a slip ring for our unique use. The manufacturer doesn’t like to make it due to the requirement is so few.
If you’re looking for the procedure for DIY slip rings, you’ll get it here. After you read the complete article, you can make these rings effortlessly. So, without any further delay, let’s dive in.
Why do we want to use slip ring?
Slip rings are also known as collector rings, swivels, electrical rotary joints rotary, electrical interfaces, or rotating electrical connectors. They are the most common motors used in various applications from healthcare to technical sectors.
The primary purpose of these devices is to convert electrical signals or data from a static component to a rotating part. We use these rings to impart dynamic resistance in the rotor windings by controlling the analog and digital systems.
Some of the advantages of these rings include the following.
- Controls the motor speed effortlessly and converts the static components into rotating components without a hitch.
- High initial torque compared to the other motors.
- Achieve pull-out torque even at zero rotations per minute.
- These can be operated at a lower current when compared to the other motors. Hence, they are highly efficient in reducing the usage of the initial draft.
How to DIY slip ring
The designing and modeling of these rings vary according to their functionalities. For instance, there’s a significant difference in the structure of these rings used for CCTVs and heavy-duty drilling machines.
The fundamental procedures involved in preparing these rings include ring selection, sketching, collecting equipment. Remember to include multiple brushes on each ring to ensure continuous contact with the ring.
In this section, you’ll learn how to make the DIY slip ring in detail.
1. Pick a ring
Before starting the ring’s manufacturing process, understand the reasons behind manufacturing it. This step is crucial as different rings are used for distinct purposes. So, make sure you’re clear with the specific usage intentions.
Moreover, further steps such as drawing, manufacturing, and testing become effortless and simple based on your slip ring selection.
2. Make Some Sketches
After selecting the type, it’s time to sketch. Draw the required components for manufacturing. In general, the slip ring electric motor comes with a fixed carbon graphite brush along with the rotating centerpiece. This rotating centerpiece is made of metal alloy.
Suppose you’ve purchased any slip rings manufacturing kits. In that case, they usually consist of all components required for the installation process, including copper wire, flexible metal wire, electric motor slip, extensive slip, an extra couple of cables, etc., based on the slip ring kit that you’ve chosen. These sketches are highly beneficial to manufacture accurate matches using the desired specifications.
3.Choose the Material
After preparing the sketches, it’s time to identify and collect the required materials. The temperature rises due to the large initial current flow through the slip rings. So, make sure you include the plastic contact material in the preparation process that resists high temperatures and prevents injuries or accidents. Moreover, most manufacturers use ABS plastic rotational components.
Some of the materials for electric motor slip ring manufacturing include nylon, miniature plastic tube, brass for slip ring self, carbon brush of 6*10mm for slippers, milling machines, drills, copper sheet, electrical contact connector, a few wires 5A 10A, and lathe.
You can even use circuit boards. This will ensure that the power percentage breakdown. By star here, we mean the star rating. Collect these parts from your nearest store or online stores. Make sure you don’t miss either of these components.
4. Start With the Manufacturing
Now, you’re ready with the drawings and material selection. So, start your production based on the slip ring you’d like to manufacture. However, for standard slip ring manufacturing, start by finishing all products before beginning the milling. The process of slip ring assembly is quite crucial.
However, it’s highly beneficial if you make every single component like housing and mounting the pieces. The best way to start the slip ring assembly is by following the step-by-step procedure as included in your drawings. It gives you a perfect mounting, and you can so slip ring assembly.
If you follow all the steps from your sketching, you get the required slip ring assembly as you desire. For general slip rings, use LED light to test the carbon graphite and brass parts. If you observe continuous blinking of the LED lights, it’s an indication of an improper manufacturing process, and something needs to be set right.
You can even use a standard 230V AC 3A teaser to check the functioning of the connectors before installing slip rings in the device. If all the connectors are working, it transmits the electrical signals or data from static components to the rotating parts.
Things to consider when making slip ring
The manufacturing of slip rings is pretty simple if you consider a few general factors. Or else, it seems complicated and impossible. So, to make the manufacturing process precise and straightforward, here’re a few things to consider while manufacturing.
Identify primary specifications
In general, the materials and manufacturing process change based on the type of slip ring you’re manufacturing. So, it’s essential to identify the primary specifications required to manufacture.
For suppose, if you’re manufacturing a USB slip ring, a few primary components include Video, Ethernet, and power specifications. At the same time, the secondary features include weatherproofing, anti-abrasion, wire sets, and insulation.
Hence, one cannot guarantee that the manufacturing Pancake slip ring also requires the same components. That’s why it’s crucial to identify the primary specifications before starting the manufacturing process.
Choose the right materials
There’re different types of slip, and each variant requires additional components. So, selecting suitable materials play an essential role while manufacturing. If you choose inappropriate materials, you get adverse results and fail to design the specific device to convert electrical signals.
So, make sure you select suitable material like the miniature plastic tube, DuPont wire, mounting devices, extra wire sets, etc., based on the slip ring you’re manufacturing. Choose the components carefully from reliable manufacturers after knowing about the complete product info.
Making a slip ring isn’t as hard as you think. All you need to do is focus on the right components to make a DIY slip ring because numerous types of slip require different parts.
If you’d like to prepare a premium slip ring, collect reliable components from top-notch manufacturers by understanding product details. Also, optimize your slip ring for only specific purposes for utmost benefits.
