Motor test - input appreciated.

Perendev-like prototype in progress. Free peek, open source, etc.
http://www.magnet.gr8.se - updated along the way... movies will come if it works.
Input in this thread appreciated.

Greatwork so far.
What kind of magnets did you use ?
Did you put a hole into neodym magnets and did you screw
them then to the rotor ?

How do you want to do the shielding ?
You need a few iron plates in a specific angle
in front of the magnets almost half to the center...

Good luck.

Regards, Stefan.

Kind: Neodymium.
Hole: Already there
Screwed: Yes, with angled head. Steel screw - if need be, stainless available.
Shielding: Will first look at and feel behaviour to determine location if necessary.
"specific angle": Do you have more info?
"half to the center": Can you be more specific?

Don't we _love_ this?

Steel screw is bad, cause you make a shortcircuit of the magnetic flux from the
upper surface to the lower surface.
Use nonmagnetic screws only.
You could fix also a small iron plate onto the upper screw head
with some airgap between magnet surface and iron plate,
use some plastic sheet or something like this, so you
have a small airgap between magnet and iron plate
both being hold by the screw.
You probably have to form the ironplate this way, that half
of the flux can get out of the hole
and the other half is shielded.
when now the rotor moves versus the stator it will first attract the
iron plate and then finally sees the repelling magnet field of the
rotor magnet and the rotor can turn on.
Without shielding these motors will never work.
I also think the Torbay principle is much better than the Perendev principle,
cause it will generate much more torque and thus power.

Steel screw: Stainless non-magnetic on the way. Thanks.
"iron plate": Interesting idea, solving the shielding and adding attraction when needed, on the aproach to the stator magnet.
Torbay: VERY interesting. Yes, Perendev has both positive torque and repelling/resisting, hopefully the positive will "win", so Torbay... IF we get to see, use and reproduce it, will be great. Hope it does not get bought and destroyed...
