Working Attraction Magnet Motor on Youtube!?

Hi  xpenzif,

You have some interesting designs with  this split  washer device,
Maybe at some point too even get some static electricity in there somewhere. 
But can we go back to the original design for replication of the
original effect. And a longer video. I wonder if the ?effect?
Is just the magnetization of the screws.
One step at a time please.
Thanks.

The motor in the video was made out of a piece of pvc, the magnets are(I think) Nd45, definitely with poles on the smaller ends.
Screws aren't really necessary, you can build one by cutting washers in half and grinding one side down. Here's a picture of part of a tiny spindle for a desktop toy using the washer design:

This design makes it easy to adjust the angles the washers relative to each other; less change in angle=more torque, more change in angle=more speed, less torque(this can also be accomplished to a degree by changing the magnet arm angle).
The above design uses a lot more magnets. I recommend a shaft made from a non-ferromagnetic bolt.

Good stuff Xpenzif

If you used Cardboard Pipe, instead of the PVC you could bury the screw heads instead of having to flatten them.

I have used HD bearings also on test rigs and although they are loose, they are not loose enough for small interactions. Some mini RC bearings top and bottom with a lathed down shaft inbetween, will give a really loose Rotor and these interactions shown in your video should speed it up very easly.

Look forward to more details and more videos, and will defo be up for quickly replicating this.

Sean,
Great idea. Better still. If you want to use PVC just drill a large (head size) holes where the screw head would go. No grinding screws and the placement would be more exact. Just lay the screw in place with the head inside the hole and add a bit of PVC glue. This is getting my building juices going. Waiting for more video and more info of the original before deciding to start. Need details such has how many rows of screws, size of pipe, size and type of screws, size and type of magnets, etc. Got PVC, PVC end caps, stainless steel rod, roller skate bearings, hardware store down the street for screws, and tons of different magnets (from previously failed prototypes). Just need details and a better proof video.

Later,
Tom

Hi Tom

Yep, if this is for real and no trickery has been used, then very interesting indeed. I wish the video had been shot with atleast a bit of voice over to rule out any of that sort of stuff must admit.

I think even drilling the pipe for each head would be a long job, seems there is probably about 40-50 screws used there. If PVC pipe is the only option, then another method could be to mark your PVC pipe with lines and then heat the screws up, so as they are placed, they melt into place as such.

Easier option would be to get angled shafts of metal and simply stick them on, but trying to think what would be suitable.

Cheers
