Orbo blueprint and theory

OK,

More Q's.

Pls confirm: Going clockwise around the rotor, the magnets are SN SN SN etc (N leads 1st) about the circumference of the rotor, i.e. N POINTS clockwise around the edge

..NOT radial edge-to-centre: i.e. not edge sees N, centre sees S


The numbers of magnets. Seems to me that the stator needs an odd number and the rotor - some other higher number, most like even.

EG 5 Halbach groups about the outside on stator, 4 rotor plan magnets (N out?)

Yes / No ?

The angles:

rotor magnets square on, stator Halbachs say 20 deg slant?

How does the angle affect all this?

Hey all:
   Just a bit of observation here. I look at the picture of the steorn person holding the proto running and then at the display case and I see a real problem. In the proto, its running wide open to the air. Not a big deal on that respect. Now take a good close look at the display case. I would think it has the sides way too close to the spinning rotor. Can you say wind currents. Lots of drag. That would soon make the plastic get just a bit on the warm side. Maybe even hot. Hot plastic likes to warp. Warp the very thing that is holding the bearings and presto, worn out bearings.
   Just a bit of thought on my part. But I would bet that thoes bearings were not movable and therefore had a side loading problem causing a lot of wear.

For the stator angles, its 30 degree but its a complete mistary about the magnets all around it, its like he will need to make a much better plan because right now we just dont have enough infos, he know how to do it but not us...

just take you time and explain better, dont assume we know the motor, no one know, also all the problem is related to the halback array, you show images that just not fit all together

are the magnet in the stator are little square magnet like this http://www.kjmagnetics.com/proddetail.asp?prod=B333 ?
