Working Attraction Magnet Motor on Youtube!?

Another possible problem. I do not see it mentioned anywhere how the magnets on the bracket are arraigned. Yes I know the poles are at the end but is it NNNN or NSNS or SNNS or NSSN This can make a big difference as if they are the same then the pull power will be different if the fields are alternating. Magnetic field interactions will play a significant part here.

Hey folks,

Pretty exciting stuff.  While i'd agree that replication should probably start with actual 'replication', copying exactly what we see (pending further info from xpendif).  However, it occurred to me that you could make very neat wedges of steel using a hand notching tool and some galvanized steel duct.  Wiss makes one, model HN1V, that creates neatly curved wedges of material.  It would be rather thin, but the shape would be very 'neat' and it could be made very compliant with the outer surface of the rotor, improving tolerances.

Google Wiss HN1V, most HVAC pros will have one, and might even let you gnaw away at some scrap duct for a few bucks.

this has puzzled me since yesterday, have a look at the attached femm picture. when the sharp end of the half washer or the screw (to a lesser extent) gets to the magnet the magnet flux strength drops to nearly half, even though the flux strength is high in the washer or screw, the magnets in the stack above or below would be at near normal strength, would some sort of 'wave' motion be set up as the thing is spinning ? going from one magnet to the next up and down the stack. or is it femm acting up somehow ?

Still not 100% convinced, hope the chap pops in again soon. I run this up quickly in the lathe last night, i don't want to start drilling into these until i know what is required , but for the time being will hot glue screws and things to the rotors..

sorry if im butting in, i havent really been a part of this thread, but something that might have influence on the origional, if the inventor used a grinder to flatten part of the screw head, this can cause a magnetization of the screw. Something to think about
