Tri-Gate Motor (TGM)

[Magnerazz]

There are better sources than buying toy kits at retail. I bought 128 1/4" N42 grade neo cubes on sale from CMS magnetics a few months ago for less than $30.
These things are strong, but they can be glued down on many surfaces with a hot glue gun. It won't hurt them if you use the low temp hobby type but the glue is barely strong enough if they are too close together. They have many different sizes shapes and strengths at decent prices. The larger the quantity the better the discount. I use Vizimag, a $40.00 2d graphic finite element analysis magnetic field program to model different arrays, then export the array design into a paint program and print it out full scale. I use light card stock and fasten it to a sheet of modeler's plywood with permanent strength double sided tape or spraymount contact cement, then hot glue the magnets to the pattern. Makes for quick experimental prototyping.

Thanks Razz!  Good prices!  I'm going to order the $15 set.

I decided to go with the $25 set as you get 3 times more than the $15 set.. only $10 more and 3 times more.. can't pass on that deal.

  The TGM pictured will not work. The gates would all be reached at the same time creating a lockup. There has to be more of one or the other to offset the gates meaning you need at least two to one and I would suggest having three or more to one so that three or more are pulling and or pushing one thru a gate.

I drew some lines to see if the gates are offset and it seems to me that they are.. one end of the rotor is at the tip of the gate and the other end is in the middle of two gates.  I have attached a graphic.

Hi Jason, it looks like you have much to learn about the gates. The design you posted has several gates but it has three large gates that all three arrays will hit at the same time. The three large gates are either at the entrances or at the exits depending on the polarity setups.

If you go back and research some other magnet motor threads you will find out what I am talking about. I don't want to discourage you and I am only trying to help you save time because there are a lot of us who have and or are still working on such designs. We have all already found out that you have to have more of one array then the other array and you have to have at least a three to one ratio. It is much more complicated then what you have pictured.

Keep on brainstorming, you may just figure out what we have not been able to. Good luck and keep us posted.
