For a lamp in which an axis should rotate, I was looking for a way to transfer voltage to the rotating axis. So I developed the option shown here.
In the hardware store I bought copper connectors with an inner diameter of 15mm for pipes and cut 10mm long pieces here. Slightly sanded the edges and soldered a wire.
One of the rings is placed on the axle from below. The wire is guided upwards inside the axis. The other piece is put on from above. To fix the rings, I heated the ends of the axles a little and deformed the plastic material so that the rings could not come off again.
The axis is guided in a part that contains the motor for driving. I have provided sliding contacts on the side. In this way, the axis can be supplied with electricity via the carbon brushes.
I use the carbon brushes in the wrong orientation, but this keeps the construction as flat as possible.
I use this parts:
2x screw M3x20 (securing and contacting the carbon brushes)
4x M3 nuts (2x motor and 2 for carbon brushes)
1x Motor
2x carbon brushes
2x pices of cupper pipe with inner diameter of 15mm and 10mm length
