Hello Everybody,

Sorry I have not gotten the promised simulation files up online yet. I just spoke to Maran about this today and I will post the dxf's of the pieces I have currently setup. I was trying to wait until I could find the time to put the rest of the screws and bolts into the model but it appears that I am not finding that precious window I need to do it. So I'll at least post the pieces I have made so far and just update the files as I finish it up. The only thing I don't have modeled are the brackets to mount the rollers on top of the stator pieces but I'm assuming that most people would just make some makeshift ones out of sheet metal anyway so I won't stress about that too much. I am not at my normal computer right now so I will post the existing part files tomorrow afternoon.

God Bless,
Jason O

Hi Everyone,

As promised, here are the updated screenshots of my CAD drawing. I actually did find the time to put all the screws and nuts into it. I also converted all the parts to .sat files which can be ready by AutoCAD. if anyone has any specific preferences let me know and I'll convert them to another format.

God Bless,

Hello again,

I've attached a zip file with the CAD drawings of the relevant parts. Here are a few notes about the model.

- I designed the rotor cap for some custom arc magnets that Dan LaRochelle has on hand but because of the rotor hub's layered design, you can simply replace the Rotor Magnet disk with a different one that would fit your magnet assembly. Since I designed it to fit rotor magnets that are 0.5" tall, perhaps using a series of small neo arc magnets that have the same 4" radius as Dan's will be a sufficient. The original arc magnets that Dan has are 4" OD, 3.5" ID, and 0.25" square cross section so I needed to use two of them to equal the height of the stator magnets I chose.

- The Stators are made up of two neo magnets separated by a steel core to approximate the tapered shape of the original wooden Torbay model. The magnets pictured in the model can be purchased at www.kjmagnetics.com on the following pages:

As for the plastic parts, the largest piece is the base, which is 12" in diameter and made of a 1.25" thick piece of plastic. In order for this to fit onto most CNC mini mills, the base could be sectioned up into quarters to fit the size of the cutting table. The next largest part is the rotor cap, which is made out of 1" thick plastic, 8" in diameter. For this design, I changed the 360 degree spiral to a 150 degree spiral but I can easily change this if necessary. The rest of the rotor and stator pieces are made from 1" and 0.5" pieces of plastic. But you should be able to see how much you will need from the drawings. If not, let me know and I'll be glad to give you a more precise answer :-).

God Bless,
