Working Attraction Magnet Motor on Youtube!?

[xpenzif]

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.

Man.. interesting stuff.  I see the spiral taking shape in your designs.  I wanted to know more about your magnet set up.  Can you explain exactly where the north and south poles are? Is each magnet in the same orientation, or does it alternate?  Anyways thanks for sharing.

You are just a prize arsehole!

I think Stefan should delete this.

Thanks for the details. While I'd like to replicate the experiment exactly as you have shown it in the video, I'm curious if you have a video of this last design in motion. Also, what are the exact dimensions of the magnets and the angle at which the rows of screws are slanted with respect to the cylinder generator line? Hope many people can reproduce the device as shown and then go further with the improvements. All the best.

I like your design,
Just one question, did the washers or screws become magnetised after time and did it change the performance? If this was the case would a set of identical magnets with oppersite poles placed in the sytem help?
Kind Regards
