Working Magnetic Motor on you tube??

[Andyteee]

any one thought about takeing the bearings out of an old hard drive or PC CPU or PSU fan ? or are they to small ?

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

Nice one Craigy
Was wondering when you were going to join us TUT 
And do not give us that excuse of Xmas/New Year visitors etc etc 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.



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.



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



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

Cheers
