Magnet Motor from Argentina, part2

[Craigy]

Hi guys,

I am playing with shields, But that may not be the correct term.

Now on the torbay motor i have fixed all stators and constructed a  Guillotine type of mechanism that sits between rotor and Stator.

The placing of said shield is critical, as we know from some of the posts done by allcanadian. The placement detemines what lateral force is on the shield. I have aimed at equal forces on either side. This is only an approximation because of the nature of the rotor , which in my machine has 13 magnets facing the stators and of course is circular.

Now i have to critizise my own video of the test i performed. what appears to be a good demonstration of shielding is in fact a demonstration of attraction. The rotor is being attracted to the shield which moves the rotor. So what is happening on my Guillotine?  I belive the same is happening.

When the shield is up and out of the way of both stator and rotor the torbay finds its neutral spot and settles there. When we drop the shield down the guillotine , its presence unsettles the magnetic field and the rotor is at first attracted by the steel shield , but as the rotor moves away from equelibrum towards the shield the other stators begin to act upon the rotor , so that the point of equelibrium is projected further clockwise so that the rotor rotates.

The energy required to move shield up and down is very small. i have used the cam i was using originally but this time without the stator lifting magnet. This cam pushes the shield down easily , timing is perhaps 10 degrees in front of the rotor ( As per standard torbay), The Shield then pops back up again because i have a spring attached that brings the shield back to vertical.
This requires tunning, the time the shield is pushed down by the cam i think affects how well this will work, but once the cam has passed by, the spring has no problem in raising the shield .

So we are not so much shielding the field as dangling a bit of steel in front of the rotor, I don't know but i feel it is a worth while avenue of investigation, so i will be making lots of little Guillotines this weekend

Wish me luck

Hi all , heres a photo. The shield used there was unmodified from a hard disk,  apart for a hole drilled to take the spring.
Since its shape has not been determined by me, i am trying different shapes of steel. Mainly because i want the spring pulling the shield up from the side and not on top whereit is at the mo.

excellent work Craig, I still from time to time pop in to see what youve been doing, hats to ya.

I'm still pursuing Sms device, if your interested pop into yahoo to see my open tpu, which is a work in progress, just for your viewing.

theres still alot of things happening on this forum regarding it.

Your doing very well.

hey craigy,

have you tried using a double action occilating lever like in gravity motors at this site to lift or lower the shield?

lol

The shield as shown in the photo worked well when there was just one of them, when we add more and more shields the rotor has more and more to be attracted too. This may be useful in the wankel type of motor where the the electro magnet goes, will try if i get the chance to experiment.
idea is not dead yet, i have another angle to explore.

Cheers
