@CLaNZeR,

In the picture you posted here: http://www.overunity.com/index.php/topic,3871.msg68193.html#msg68193 it appears that the magnets on the rotor are cylinders. The magnets B448 recommended, however, are rectangular. Am I missing something? Sorry if that question has already been answered.

Alsetalokin used Rod magnets but the designer OC thinks block magnets would be better, so for now going for blocks, but the design of the rotor will allow Rod magnets to be placed easy enough if we find blocks not working.

As I said before I do not think the exact sizes really have to be spot on, but it is more the effect that is the key.

Should be an exciting couple of weeks

Nice, what you are using to cut your plastic like that!

I have a scroll saw and i broked 4 blades just trying to cut my rotor and its still not finished lol

I need help

Sorry mate, no quick fix when it comes to hard labour.
I cheat LOL, I have a small Desktop CNC machine that does all the hard work for me.

Hello All,

Still working on the CAD drawings for the motor. I ran into a small discrepancy in the given dimensions so I thought I would pass this along to you all. Alsetalokin mentions that the radius of the rotor disk is 2.875 inches with 0.25" slots for the magnets. He then goes on to say that the inner edge of the slot is 2.5" away from the center of the disk. However, after drawing this up in AutoCAD, I noticed that the distance from the outer edge of the slot to the edge of the disk appeared to be 1/8" smaller than what seems to be shown in photos of the actual device. So I increased the radius of the disk by 1/8" to 3" and now the CAD drawing seems to fit nicely with the photo when overlaid onto it (See attached images). Can someone who has contact with Alsetalokin pass this information along to confirm what I am seeing here? I don't mean to be too nit picky about the specs but I don't want to take any chances with the distances between the magnets.

Thanks,
Jason O

Jason, I don't think you're nitpicking at all. Replication should be done exactly as @alsetalonkin's device. That's why I don't think also we should use rectangular magnets but should use the exact cylindrical magnets @alsetalonkin uses. What are they? I second @Jdo300 in asking someone to verify these issues with the actual constructor (not with someone who gave the idea).

Ah, I guess one of my next project will be to do a CNC machine http://www.instructables.com/id/How-to-Make-a-Three-Axis-CNC-Machine-Cheaply-and-/
