Low Friction PVC Stator/Rotor

This stator/rotor design is based on one I originally saw used by Transdimensional Technologies, Inc. It is very low friction and the electrical wires coming from the power supply arrive at the center of the rotor from directly above and below.

Note that of the wires coming from the power supply, one is coming from the ceiling and the other from the floor (ground wire). This reduces the chance that movements of the devices will be derived from attraction to or from these wires. The tall black legs are ABS and cause the rotor to be relatively centered between floor and ceiling.

*The actual rotor is interchangable. This is a lightweight one made of plastic hollow bars hot glued together.*

Close-up of where the stator meets the rotor. The top of the rotor has a small screw hot glued on top of it with the tip pointing up in this picture. Its threads have been filed off. After soldering the two connecting wires to it, it was then painted with a thick layer of liquid black electrical tape. The stator has a robertson screw screwed into from the bottom such that you can see the head of the screw clearly (see picture below). Any exposed threads have been filed off and as much exposed area as possible has been painted with liquid black electrical tape. The tip of the screw from the rotor is sitting inside the head of the screw head from the stator.

*This is the bottom area where the stator and rotor meet and is made the same as the top area but is upside down.*

*These are the parts of the stator under construction (the parts with the screw heads mentioned above).*

*Paraffin wax was poured into the various parts for further insulation. Ignore the two caps and two wires directly above the ladle. They were not used in the end.*

September 19, 2005 - I made the stator taller while keeping the rotor vertically centered. This increases the distance between any device and the horizontal top stator bar, and any device and the bottom horizontal stator bar. This decreases the chance of electrical interaction.
