Working Magnetic Motor on you tube??

[hydrocontrol]

So if you want to retard the drive stator why not just take a 3/4 inch copper pipe, cut it in half, then place that half on the backside of the stator magnet (away from the rotor) . That should induce drag on the stator. Why induce drag on the rotor ?

Seems harder to get these new Stator Magnets to latch compared to the Bodged Stators I used before the correct ones turn up.

Spent a couple of hours inserting washers one at a time making the Stators Higher or Lower to try and get the easiest config and also moving the Airgap distance bit by bit, bloody boring stuff I will tell ya LOL

This was without the HDPE surround.

What i have found is to start the one stator first and than immediately then start the rotor. doing it this way two out of three time i get latch up.
u probably have tried this, but though I'd pass it along anyway. Will send pictures later.

Hello All,

Something that I just found here OC_MPMM_c.JPG, and was thinking about.  Al said, that at one time he used nylon screws in the stators (for the bearings) but it was not firm enough, so he changed to a metal screw.  We all are using Brass screws, but that is not what is pictured in that picture, and it does not look like stainless. 

If someone could ask Al if these screws are normal nickel steel screws, or stainless, or what for the stators.  It could be significant what type of screw is also used, ie..drag, eddy currents, etc.

Believe me, when I say what you put there affects the bearings, which already have a lot of drag from the magnet, 1/16" above.  I began assembly of my bearings and brass screws last night, and played a bit with the magnet on top, seperated by a fiber washer.  The drag is tremendous.

Please find out from Al what the stator bearing screws are and post it, please!  Thank you!

@ Butch
Your rotor looks like it is cut different than Al's.  Not sure if this would matter, but it might. 

Cheers,
Bruce

from my notes on the stator...

"A Delrin cylinder 0.625 OD x 0.500 long, with axial 0.375 dia hole bored all the way through.
Then one end bored out to 0.500 dia x 0.250 deep, to receive magnet.
Then other end bored out to 0.500 dia x 0.175 deep, to receive bearing.
Magnet and bearing light press-fit into the cylinder.

Magnet is K&J 834DIA, 0.500 x 0.250 x 0.1875
Bearing is generic ball bearing, ferromagnetic, 0.500 x 0.1875 x 0.125

Assembly is mounted to baseplate with a SS #4-40 SHCS with the head trimmed for clearance, magnet up, with a little SS washer between the bearing inner race and the baseplate, for clearance and stability."

Howdy All
Well here's my setup and a bit of data
Rotor bearings - Gulf Bearing # R1-814-HA3 or R188
Stator - Bearings, # R3-HA1
