got over the sticky spot

K,

18 hours of shaping a magnet and I have this - comments very much welcome.....

highly compressed - if you need to see a higher res version say so - for now I'm going to replace the old mags with some neo's I'll source tomorrow - then close the loop.

ScottClarke, thanks for the video. It loads very fast and is of excellent quality. Will wait eagerly to see tomorrow's results. Good luck.

This is very interesting to see. I have like 300 1/8 x 1/8 neos i can probably try to duplicate this and see what i get. Can anyone come up with some measurements of a prototype? i had built a wheel that goes 300 degress but stops at last magnet. this might solve that problem. I have to try this.

Duranza,

You will need ferrites too. The magnet responsible for the 1way pull took 18 hours to shape. - If I had known the shape I needed it would have taken 1/2 hour!

This took over 12 months to get to this point. I obviously do not have measurements yet - they will come with time. The specifics will become puiblic knowledge - have no fear.

For now I have what I am certain can become a self runner with a slight excess. If/when this works I intend to reproduce a much larger multi rotor version that can generate some real power.

Understand I am not holding back anything at this point. Trial and error has led me to this and I simply do not have the specifics. I am not sure of the field shape, strength nor dimensions of the whole. My main concern is the shaped ferrite - without it there is no way it would work. Reproducing it will be troublesome - especially if using different shaped magnets. I do not have a source for these - I have had them for at least 10 years in the bottom of a tool box.

What I am certain of is that neo's all round will not work - been there done that!

Regards,

Scott

That's how i got the wheel to go 300 degrees... i used neos for the rotor and weaker ferrites for the stator. i have tryed to grind the last ferrite to make it go over the sticky spot but no luck. I like the ball bearing with the neo idea. I looks like it evenly spreads the flux around. I'll be very happy to see something come out of this.
