Self-sustaining DC Motor, using old 5 1/4" Floppy Drive Magnet

[shylo]

Hi smokey, What was the dia. of the motor you were using? Also what was the distance from the disk to the magnets in the motor, the length of the shaft?
In the last photo Gylua shows there are 10 little south poles and 9 little north poles on the outer rim, where he indicates the big south pole. Not sure if that is important or not.
I've noticed that spinning a mag wheel with all the same poles facing out creates an opposite pole in the center, and projects outwards, but that was with magnets around the perimeter not fully covering the wheel and not alternating.

Ok ive got all the bits.



Motor is a 5v DC.


Do the dimensions of your setup seem similar to those in the pic?

Here are some preliminary tests. This one has the magnetic side pointing down. 6V is applied to motor my hand for probably one second as you can see on the vid. Then motor is allowed to spin down by itself. it takes quite a while to do so.

And in this one the shield is pointing down, still taking a while to stop.

Hi pomodoro, That is a long time. It would be nice to see a run with just a flywheel of equal dimension and weight.
Will steel objects stick to the outside of that motor? Just curious if the housing is saturated.
Thanks for taking the time.
