There is no question about it, Brady uses the repulsion, their site even says so. I can only imagine that the best way to reduce eddy currents for longevity would be to have the magnets well within their load threshold and use magnets with a relatively high gauss level. The shielding may also reduce eddy currents as it would constrict the approaching parts of the field preventing them from reacting as strongly over the same distance, so the overall build up would be diminished significantly if each magnet has a smaller focused area of interaction.

The angles, the tri rotor offset of half a magnet, and shielding (mu-metal inserts on the approaching sides) seem critical, it all seems to be set up in such a way as to tip the balance so the direct initial repulsion of one magnet in the rotor pressures the next magnet in the offset to pass the parrallel point of the next stator magnet, concluding in a repeat to the next.. locking it into an asymmetric interaction.

I totally agree.
The method i am using, is to divide the stator in 3 separate parts, overlapping by half a magnet each stator part. (Thus i dont have to make 3 stator- and rotor-parts). Granted, mine will give much less torque because of this - but it is a toy, and proof-of-concept, only.

Update on my replication:
- i got non-attracting stainless screws to hold the magnets
- i got metal plates to attach atop magnets on rotor, to separate with thin plastic sheet, producing frontal shielding, and some initial attraction to upcoming stator magnet.

Not much time, as other projects, family and a 5-day out-of-town trip is "in the way" ;)

BTW: The assymetrical interaction, over-riding the repellation, is a "loose-some - gain-some" situation. This means the "net" output torque is much less than the total magnetism/energy in magnets. It would be so much better to get all the magnetism/energy to do an "un-interrupted job" - and possibly others have succeeded/come closer to this, but it seems they always use electricity/electromagnetism to overcome the lock-up.

I still follow the www.befreetech.com project a lot - they just had meetings/demonstrations in Cleveland and Chicago - anybody know how they went?

Hi Mi,

It looks like your motor design is just like the Tri-Phase motor project that I have been working on for some time here: www.fdp.nu/perendev.

That design can work buf if you go with the all repeling design, you will need to design the shielding to cut down the repelling field on one side of the magnets. Not to say it is impossible to get working without them but it will be worlds harder to tune. I have a prototype that I have been playing around with for some time but I have yet to get it to run in repulsion mode. If you can't get yours to work, you may consider using magets at 90 degrees as I proposed in my article the 90 Degree rule Theory here www.fdp.nu/free_energy.asp?book=90.

God Bless,
Jason O
