I don't know the exact part number. He did mention the dimensions of the stator bearings though (which are noted in the blueprint drawings) and noted that he got most of them from Stewart-Warner. Beyond that, I don't know.



Hi Jason and Bill

From the ocmotor pdf:-

Parts
-Perspex baseplate
-Delrin stator
-R834DIA magnets for the stator
-B448 magnets for the rotor (OC)/??? bar magnets polarized end-wise for the
rotor (Al)
-10 nylon 8-32 screws for stator magnets
-tiny ball-bearings for stator magnets--RC helicopter spare parts.
-Stator magnet/bearing plastic housings/holders

I did a google search on ball bearings for rc helicopters but could not find what material is used, without me calling the rc guys up i'm assuming here that they are magnetic.

Well you guys dont know me from Adam, but I have been here watching for a looong time... I am extremely interested in this particular project, I have submitted the plans as kindly provided by Jason to my local machine shop friend... I have asked him to supply me a quote for 10 of the units... if there is any interest please let me know... I will post the cost each hopefully by the end of today. I am not sure how expensive it will be but will gladly send them at my cost plus shipping. Thanks

I sent you a email but would like one and in Canada

@Dom,

The rc helicopter guys said they have no idea what they are made of. I ordered them anyway--an apache type spare bearings.

Go here   http://www.greathobbies.com/index.php   and search bearings then you can see them all. also recommend just visit your local R/C shop and carry a magnet and shop.

np, i'll check the hdd bearings with a magnet soon, i don't think they are magnetic

Has anyone sourced the other parts?, bearings, magnets for the Uk?, I have the link for the German magnet company, but would prefer somewhere in the Uk.

Hi Lakes

I have some 5mm * 20mm Neos on order from this UK company. Could not get 6mm.
http://www.first4magnets.com/bar--rod-magnets-1-c.asp
http://e-magnetsuk.com/magnet_products/neodymium_magnets/rod_magnets.aspx

I have done a second Rotor to accompany these.

For Bearings try http://www.technobots.co.uk/acatalog/Online_Catalogue_Bearings_377.html

Hope this helps

Cheers

Sean.

I'd also suggest the McMaster Carr website as a source for bearings (and almost anything else you could possibly ever want). http://www.mcmaster.com/

Hey UZ, please count me in also. I sent a PM.

I ordered magnets today.

You know I was just giving up on my own Magnet Motor project, ready to throw all that junk out, and this comes along pulling me back in!

Hi
Been Snooping and came across this spec.
These are magnetic, but got a hunch I'll be purchasing more bearings
later of the same dimensions, but different construction material.
Please see attached

Got started on my own proof of concept , magnets are 6mm by 12mm on a rotor i had lying around. I will cut another att the correct diameter , but without cnc that takes time. The magents are a friction fit into the slots that were cut out using a 2 flute milling bit in a vertical pilar drill. The plastic moved by hand  ( oh Dear !) anyway it gets me going..lol

I am very impressed by how well thought out the design is, especially from a materials and adjustability standpoint. Good job! :)

Played with a few ideas for the stator magnet mounts because I want them to be movable.

This seems to be the best design I can think of:

I went for a 6mm Rod lathed down to 3mm with a lip to space it slightly off the top of the bearing.
Press Fitted the 6mm end into a bit of 16mm Polycarbonate Rod. Will use a little bit of glue too seal it.
Tapped a 3mm thread on the end.

(http://www.overunity.org.uk/ocpm/Ssax1.jpg)

Mounted the 6mm OD and 3mm ID Flange bearings either side of the holder.
Press fitted the Brass rod inside the bearings by doing the nut up tight and then removing it.

(http://www.overunity.org.uk/ocpm/Ssax2.jpg)

The block is held in place and can be slid back and forth.

(http://www.overunity.org.uk/ocpm/Ssax3.jpg)

I should now be able to lathe out the 16mm Rod to press fit the 12.7mm Stator Magnets.

Cheers

Sean.
