Tao,

You are such a tease

cisco - this device is multi directional it can go either way/ it just depends on where the rotor poles are facing when the device is started as it is going to move in what ever direction is closest to its target.

as to sudden up gradual down and such i think that the best rpms would be accomplished by sudden up and down though this would cause snags on the bellcurve if the curve is to steep so i think "as sudden as possable with regards to rotation" is the best answer. also i think now that i mentioned that the device is reversable (torbay said it was) that the bellcurve is semetrical as depicted in taos design.

question - we are all designing prototypes that hold down the stator magnets 360 degrees minus the one that is up.... in torbay's design he only used a half circle as a cap. (probably curved on both sides and dipping down in the middle) is it possable that we still have something wrong? or is it just a differece in designs between his wooden (weels to lift stator magnets) and his metal one.

i will begin by replicating his wooden one and i have already begun today. only have one question here. i will be using the following rotor design could you take a look and let me know if you think it will work to begin with as i do not have a disk magnet.

thanks danny

ps would bending a piece of metal (magnetically atracted) across the front of the three magnets help "smooth" out the magnetic field? would it help any?

thanks

Hi Tao,
now I had finally again access to my PC and have downloaded the animation.
It is really great and I will soon convert them to a smaller size and Codecs,
so many more people can have a look at it.
Maybe you can make another version, where the lid-cap is transparent, so
one could see the inner rotor magnet ? That would be very nice and
this way one would understand the motor much better, if one could also
see the red-blue polarisation of the rotor disc magnet.

Looking forward to this and your new other files.

Many thanks, Stefan.

This is the Torbay model I am replicating. Any discussion is appreciated.

jaybird, as you know, I think it?s a good idea to replicate one of Torbay?s original constructions, so I?m encouraging you greatly. What have you decided these pictures show? Is more than one stator magnet lifted at any moment with this semi-circled rotor? Will you be using three (four) separate rectangular magnets or one magnetized through the diameter annulus (recall, calculations which tao and Stefan made showed that magnetized cylinder or toroid yields the greatest torque)? Tell us more about the lifting mechanism ? will the stator magnets be beveled? Also, is the lifting and descending going to be symmetric ? is the time it takes to lift the magnet going to be equal to the time to lower it?
