Hi All,

I've posted my video on google video,http://video.google.com.au/videoplay?docid=5291826833015915174 it's the one on post 87, you can d/l the vid from the google site by using this url:-

Craigy, I was too thinking about the ramp, I'm on this part now, thinking about it more, I think walter may have used weights to assist the stator arms back down again, look at his video, youll notice that not all the wheels are touching the bottom of the ramp disc, they seem to clunk back down, which makes me think he is using garvity, (weight) to assist in getting them back down again.

Cheers,

Dom

You may be right, his machine is certainly a monster, why on earth he didn't post more pics of the cd size machine is beyond me.
I really don't want to add weight if i can get away with it, on my machine so far the initial kick to get it going is nothing compared to the acceleration it gets after passing 2 magnets. i will try though, i will load my stators down with brass washers and see what that does..
I have noticed that the amount of kick up, is proportional to amount or initial rotary force. i.e. the bigger the swing on the stator being lifted, the bigger the initial kick, might need a few more magnets to lift the stator as it will be a lot heaver. Still lots of avenues to explore, not just ramp , very absorbing.

Cheers

Hi Craigy,

Weights is an option, another thing is that It may not have to travel too far up, just probably 5 mil might do the trick, so maybe using weights can be eliminated. He also uses a half circular magnet on the rotor, and the ends might have the oposite polarity, that is attraction, this is worth exploring as well, We will just keep at it, my minds been busy lately...lol

Hi Craig,

I have an idea that might help you a lot, though it may intel a bit of redesigning of your prototype to some extent.

The orientation of the magnets on your rotor looks just like the Minato wheel in its design. If you check out http://www.fdp.nu, you can see that Mr. Minato used a large stator magnet to cause the rotor to rotate; but the interesting thing is that his rotor actually rotates in the opposite direction of yours! The problem with minuteÃ,’s wheel is that the sticky spot is at the beginning of the track (back repulsion) that stops the wheel from going, but once the stator magnet is past that area, the wheel accelerates through the track, and at the end, it gets a shove away from the last magnet until it reaches the sticky spot again. But perhaps you could use that repulsive sticky spot to your advantage to life the stators in front of the track. And since the magnets are angled in the direction the wheel is rotating in, you won't have the problem you are having now with the field at the end of the track being too strong to allow the stator magnets to lower. But you will need to use stator magnets with a larger pole face though to accomplish this. The larger face will allow the stator magnet to smoothly glide over the track without getting stuck between the rotor magnets.

God Bless,

Hi Jason, A very valid observation, It appears that i have created more problems for myself using my multiple magnet rotor approach, I am doing it this way because these are standard magnets that cost 10 euros off ebay and if, and when, this replication works it means that it will be easy for people to replicate as well. The Torbay information is open to speculation. Is it one magnet , is it four?  Does it have a stronger face in one direction than another. We just don't know with any certainty. So with lots of unknowns i diecided to use multiple magnets which can be easily re-orrentated.

I have been working on the rotor all day today, i have concentrated on getting the stators down instead of torque. So now everything goes up and down as it should but now i haven't got the Torque ( half a turn at most) AAAAGGGh LOL.  I will try something similar to the minato wheel and see if a inward curve of magnets will give the effect i want. thus at the bottom of the curve dropping the stators should be easier, as for the angles of the magnets their maximum force is at 45% off the face, but i will try the other way around just in case i have missed something,

Thanks for the observations

Hi Craigy,

Don't burn yourself out, pull back at times, have a break and think about what to do next.
I've taken another snap shot of what im going to do with the rollers ontop, im actually bringing them closer to the centre. Torbays design has his wheels ontop closer to the centre rather than out more, Ive also thought of another idea if the rollers i made dont work, good idea is using roller bearings instead, i.e 360 rotation but i guess they dont make them in brass, maybe stainless steel would do nicely, I have to check on that.

If you can bring your top rollers closer to the centre, it would make it alot easier to make top ramp disc, Im going to check on Torbays video again, because by right where the stator arm which gets lifted in video, there should be no ramp. The ramp should start where the first magnet gets pushed down, that should cause the rotor section to move forward.

Don't give up
