Hi All,

In this tutorial I will present you how to make a DIY 3 channel Slip ring.

Step 1: Make Some Sketches and Choose Your Material

First I start with make some specifications and sketches. After the sketches I make some choices about the materials that I want to use. Because a lot of current can flow in the slip rings the temperature can be go up. The material I choose they are plastics that can resist high temperatures. I hear you thinking about peek, but peek is to expensive. Thats the reason why I choose for nylon. The material for the slip ring self is brass. The "slipper" what I want to use is a carbon brush 6x10mm (buy from aliexpress). After the sketches I start with sketch in inventor. In this step I think a lot of the production machines they I can use. In my case only the milling machine, drills and a lathe. In the attachment you can find my package of drawings and the full part list. (Maybe something are written in Dutch).

Step 2: Start With the Manufacturing

Now all the drawings are ready the production can be started. In my case I start with turn al the round parts, after it I start with milling. When al the parts are ready I mount every thing together. I make the cables and the slip rings with brazing together. Make sure the brass things don't touch each other. What you also can do is when your sure the brass rings don't connect each other you can fill the hole with resin. The cable and the carbon brushes ar connect with normal soldering.

I make some extra mounting block at te top to mount the slip rings to my project.

Step 3: Testing

Now the slip rings are ready to use you can start with test them. I tray everything with som LEDs . When the LEDs begin to flash you now something is wrong. In my case everything works fine. Now is a big question, how much current can we transfer with this slip rings? I test everything with 230V AC 3A and its works fine.

I hope you enjoy this tutorial and use them in your project. For questions let me know!

Regards,

Job

    This looks neat, but I'm not sure I understand the application. Will this be part of a larger project? In what way will it be used?

    We will use it for a “carnavalswagen” (see picture) in holland. Somthing rotate and we need power in it. With this slip rings we tranfer the power.
