One magnet no bearing Bedini motor

@ Wilby:

Thanks.  I have several places I found online but I was looking for a local supplier so I could "hand-pick" some of these.  This device is so cool.  I can't wait to see your replication.

@ Jonny:

My neo spheres arrived yesterday.  I did a few quick tests and, even the 1/4" spheres spin too fast!  (I got .750, 5/8" and 1/4" dia.)  Even with all of the resistance off, it stays in the center and really winds up and then........look out!  I had one fly off and hit my fridge across the room and it put a small dent in the door!  It was like a bullit.   For the small spheres, I may have to lower my base resistor value from 100 to something lower.

Great video!  I can't believe it runs on som low a mA number.  Great job.

Hi Bill,

I think just the other direction:  you would have to increase your base resistor to reduce the collector current so that the sphere magnet should rotate with less speed, hence they would not launch... 

Or you mean the small spheres need more collector current to spin faster?   I miss something?

Thanks, Gyula

Gyula:

I may have that backwards.  I will have to put my meter on the pots to check it.  I know I have these pots wired backwards from my Bedini so I may be confused.  Thanks.

Here is my latest video on this:

I am using smaller, bench tested magnets supplied to me from a good friend from overseas.  These spin really well.  The fun begins.....

took a break from winding a new tesla secondary and tossed together a quick testbed to see what 'type' of spinners i had. it looks like i got lucky, i have one that runs close to perfect vertical, and one x wobbler. i used a really small coil, no adjustment pot, and ran it at 9v input. it spins, but nowhere near the revs you guys are getting. will post a pic after i pretty it up a bit.
