New accelerating lego magnet motor on youtube

I will dig up the videos and post them when I get a chane. First of all You don't want to use pully's. Reason being you may not get exact revelutions with the force of the magnet. You have room for the belt to slide. In my first design I used a rubber band which does not work good at all because it stretches  and with the magnet force it won't turn correctly. So my second design was with a plastic gears. That works better but It wasn't perfect as I didn't have a cnc machine. It's probably just best I post the video so you can see what I am saying.

@ hanglow,

Turbo just announced that he got sustained rotation on a WhipMag device, but accomplished this by placing rod magnets on top of the stators, which stopped them from rotating, but allowed them to oscillate.  This resulted in a sustained rotor rotation of 300 RPM.

Implications:  Turbo's device is starting to look like a hybrid of the Lego device and the WhipMag, and because the oscillation phenomenon might be very important if not critical, I think the loose coupling afforded by a rubber band might be important to the Lego device.  In my mind's eye, I can see the elasticity of the band allowing the rotor mag to oscillate [hunt?] slightly as it passes by the fixed stator mag.

In your latest drawing I count two sets of six stacked objects in the stator support.  Given that the Lego plate is the shortest Lego object and is 1/8" tall, this would imply that the internal height is 6/8 (i.e. 3/4).

The video shows only three stacked objects (presumably 3/8").  Could you please clarify?

If it's a "CAD-rendering-thing" perhaps you could make each of the three stacked objects a different color (red/green/blue).

The video is poor -- believe me I know -- and we will issue purple hearts when this is done. 

Cheers,

Lego has two types of basic blocks. The thick block and the thin block. Three thin blocks equals one thick block.  In the first version I made, I made it with the thick blocks. But based on your observations and my own, the stator holders seemed too tall. So I decided that maybe the design in the video just used two columns of six thin blocks instead of two columns of three thick blocks. This was the second version I did, but you could not tell that the thin blocks where seperate pieces because of the way the software is. And unfortunatly, the same goes for the crappy video. So, I made the third version to show you the accual seperate pieces in the columns. I have attached a picture of the blocks I am talking about. Feel free to ask more questions. I am here to help.

Simple, i am the autor  .
I just thought it was enough like that.
