New permanent magnet motor on youtube from Roobert33

It would be great if someone could make a drawing (preferably a dxf file) of the drum with the exact beds for the magnets so that I can bring it to a machinist tomorrow. In the past our own Jason (@Jdo300) liked to do that but I don't know if he's reading this thread. As for the magnets, I'm gonna go tomorrow to the company that sells them and pick them up from there. It's near the place where the machinist is. Unbelievable, isn't it? I mentioned in the other theread that here in Sofia, Bulgaria it appears to be a hundred times easier to do work than in New York (not to mention the prices). Like I said, unfortunately I'll have to be back in the US at the beginning of December so will have to figure out the best strategy regarding this replication.

Took me a while to get the spacing and degrees correct for the length of drum I am working on.

As usual I try to stick as close as I can to 100mm rotor, but in the video it looks more like 150mm.

So by the time I plotted out the V-Track to suit 10mm magnets, the rotor comes out at 89mm diameter inside and 95mm on the outside.

I am thinking of reversing the artwork as such and making a mould for this V-Track. Would simply then mean pouring liquid rubber into the mould to produce one.

I guess @Roobert33 has just glued the magnets onto the cylindrical surface and that's all. Rob (not @Roobert33) emphasized the cup where the magnets are stuck to should be light although made out of whatever material, not necessarily metal (copper) as in the vid. Wouldn't it be better to have a cylinder, not a hollow cup, however, to have a flywheel effect?

whoww Sean as usual very nice job

For my small contribution , i am playing with my drum (now with 3 layers of magnets to increase the power.

Until now i have no chance to overcome the cam in my config.(but very near)

But after trying everything,  i think that  it could be an opportunity by using a short and sharp cam as per the original (Roobert33) design. So with a config in Attraction on the the nearing of the gate i can get a very strong acceleration and simultaneously a strong and short attraction. So i think that Robert use also the push of the attracted magnet on the rear side of the cam to propel the rotor.

And also the bottom part is surely absolutely necessary. (not tried yet)

On the pix it is some of my testing apparatus. All is mounted with ball bearing. But i have to improve the design   ough a good working day !! but very good fun

Anyway working or not working it is amazing that those Vgate works with every material ,magnetic or non magnetic stators ,small bars or long bars magnets outside or inside the drum etc etc.. very interesting to learn how magnets work, And perhaps with better building....?

Good night at all

@woopy,

Nicely done. Indeed, it appears you have to work more on the cam. Good luck.
