Working Magnetic Motor on you tube??

Western digitals take apart fairly easy and completely dismount from the chassis.

Hi Sean,

Looks great. 

Just a thought, i am of the opinion that the rotor magnets and the stator magnets when doing a reverse spin pulls the magnets toward each other thus forcing the rotation.  If this is true the rotor needs to be as light as possible and the stator needs to be heavier to pull the rotor.

Let me know what you think.

cool stuff sean , starting my base plate today, although am tempted to plug a few of the new magnets into the old model i have..even though the measurements are wrong. The stator holders are they just brass shaft , friction fit to bearing and magnet?

Hi Craigy

I lathed down 6mm rod to around 3/16 one end and 3mm the other.
Then I mounted the magnet in the lathe and placed the Brass Rod in the lathe tailstock drill chuck. Then just gently squessed it in. They went in nice and square and a really tight fit.

I cut some 3mm brass tube I had to make the 6mm spacers and the bearings mounted in polycarbonate mounts either side.



On the finished ones press fitted I just threaded the end so I could put a nut on the end and pull fit the shafts into the bearings.


Good luck mate

Cheers

So in this stator design, the bearings themselves do not rotate?

In Al's stator design, the bearings rotate with the magnets, and I believe they are ordinary (ie. magnetic steel) bearings.

May be significant.

LOL yes they rotate or waste of time having the bearings.
The brass shafts sit inside of the bearings as the picture above shows.

Hi Adam.

Got various Rotors on the go and at the moment playing with the 6mm Thick Rotor below that has the 5mm rod magnets in it.
Simply by removing the spacers on the stator bearings it allows me to drop them level for the thinner rotors.



Cheers
