Permanent magnet assisted motor coil designs

[captainpecan]

Moving forward towards switching it up. I'm removing the magnet rotors and moving to an attraction design to see how these special coils will work. Got my new rotors done and waiting for epoxy to completely cure. Some of you who have been following the Tinman torque force motor, you will see right where I am going with this next phase.

I've got it running in attraction mode now. I no longer have the major issues with Lenz law slowing things down just from collecting the back spike. I have a lot of tuning to do and more coils to add but it's running well so far. The coils poles are opposing each other causing the field to push further out sideways between them to grab the rotor and pull it. The original design for this concept I learned from Tinmans work on his torque force motor. His design required a permanent magnet and a coil with a tiny gap between them. This is clearly not how he says it needs to be done. But he also using a conventional coil that he works hard to increase the inductance of. I however have the permanent magnets embedded in my cores. So totally different, but the attraction concept im shooting for is the same principle. But I want to give credit for my inspiration as I think it is great design for an attraction style motor. I will be trying it out that way as well of course. I have designed my build to give me the ability to try many different configurations. This type of attraction motor, it is critical to reduce the gap to as small as possible for the best output. Here, my gaps are pretty wide. I need to make sure things are sitting properly and not going to all smack together and destroy my coils. So for right now the coil gap is large and it will be decreased. I am getting over 300 rpm at 35 volts and about 30 ma. This efficiency should greatly increase as I add coils, decrease gap, and adjust the timing. I will shoot some video when i get things tuned better. Good stuff, just wanted to document my progress.

Here is a little better view of my setup.

I will be adding a generator section to this of course. This phase is trying to recapture as much energy as possible while getting the most torque and rpm for the least amount of energy as possible. But, the fact that the gaps are pretty wide, and I've still got it running pretty good, is a good sign.

Here is a little more explanation of my design. The coils are the most important part that I am concentrating on. I believe there could be many different applications this can be used for. For now, I am using them to experiment with the torque force motor concept. Those not familiar with it, it uses a small gap between 2 like poles to project the field outward further. The combination of this, and the angle of the torque plate it is pulling inward has been proven to give a greater than double pull force. I have seen an extra 40% pull force more than double myself in my own experiments. This is a great time for me to combine these concepts. So this is what I'm trying.
