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.

Here is a little better view of my setup.

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.

Thank you captainpecan.

I guess you know, thats what were looking for. Very cool and good luck with
your testing.

Another interesting idea I had I just wanted to get written down. I checked to see the distance that my half inch wide torque plate bars get attracted to the side of my 1/2" magnets. Turns out, at just under 1/2" distance it begins pulling them together. Therefore, if I put both next to each other on a rotor, as long as there is 1/2" gap between them, there will not be any significant change in the magnets field..  this led me to this concept that may work well with my hidden magnet coils. Seems someone would have tried this before but I haven't seen it.
Problem I had using magnets on the rotor was that for my setup, just simply collecting the flyback spike had a strong Lenz drag effect. More than in a usual setup. This led me to an attraction design because I need to collect that flyback to protect my mosfets and of course efficiency. It seems I have an interesting idea to combine the attraction design with the magnets on the rotor at the same time...


Step 1, the rotor has both magnets and iron plates, arranged for best use as shown below.

Step 2, the magnet on the rotor is attracted to the coil core on the way in because the magnet in the coil is effectly off.

Step 3, when the magnet passes the core, the coil will be pulsed projecting an opposing field forcing the rotor forward. The gap between the magnet and coil will direct more flux backwards towards the iron on the rotor. This will pull and attract the rotor forward at the same time. Effectively getting 2 forward forces for 1 pulse.

Step 4, the coil is turned off and the field collapses. Lenz law states that the rotor magnet will be dragged down a bit as this happens. At the same time, the iron will still be attracted forward and it will be closer to the core at that moment. This should hopefully help negate the Lenz drag enough to make a noticeable difference and allow the collection of the flyback without dragging the motor down as much.

This seems to simple. So it's been tried before I am sure, but seems worth a look for my coil design due to the strong Lenz law effect present when permanent magnets are used on the rotor. Hopefully the combination of step 2 above giving 2 forward forces for 1 pulse, and the extra attraction forward in step 4 as Lenz drags the magnet down a bit, will give a net gain overall and get a bit more torque and rpm for the same or less energy input.

I have been thinking that the severe Lenz drag I got in my other experiment with magnets on the rotor while collecting the flyback, wasn't so much from the flyback. It was from the circuit effectively being a halfwave rectifier with that diode in there. This means it is collecting the energy in generator style as the magnet approaches the coil, then nothing as it passes TDC, gets the pulse, then collects again as the spike occurs of the flyback. This is fine for a device such as the SSG where speed of rotor is not important at all. But I do not want to capture the energy on the incoming movement. I am thinking of using a reed switch to have an open circuit during the approach to stop this drag. It seems to me as long as the reed switch is closed when the high voltage spike occurs, it should not cause any further wear on the switch from the high voltage like if it were to try and jump the gap. How have others done this and have they been doing something completely different? I am not wanting to slow down the motor function other than what is required to recover that flyback. I plan to pull energy from the system with a special designed generator function as the speed is high. Any ideas would be appreciated.

THE QUICK AND EASY WAY TO AVOID ALL THE LENZ NEGATIVE EFFECT.
IS TO MAKE THE STATOR AND THE ROTOR THE SAME. AS THE TWO REACH TOP
DEAD CENTER BOTH ARE TRIGGERED. AND VOILA.

Captainpecan,  here is the circuit I used to drive my motor and capture the inductive kickback.  I never saw any reduction in speed when collecting the kickback with this circuit.


You can drive it with almost any type of trigger circuit.  The 555 circuit acts to clean up the input signal.

Thanks, that's a pretty simple circuit!
