Simple adams motor

[boguslaw]

Hello

I have a question about the simplest Adams pulsing motor , a coil a ring with magnets and a magnetic reed switch connected to for example 12V battery.
It seems to adjust itself after initial kick to some speed and I'm truly interested how that speed can be computed and on what it depends ?

It's looks like self-regulating resonance to me and I really must understand such feedback system.

I am currently working on Adams style motor experiments, and I can adjust the speed by advancing the trigger pulse timing position of the reed switch. From what I gather from my own experience and limited (but growing) knowledge this affects the position of the passing magnet within the field of the coil core when the coil actually fires.

As far as computing the component values for speed I would guess its a formula of gauss ratio between magnet & energized coil multiplied by the timing ratio I mentioned above.

I usually just lurk here but this is the first thread where I can actually feel like I could contribute something useful. This is my first post so please be easy on me for I am only but a simple scientist compared to many on this forum, I only know what I see.

Peace

The best I can tell the simplest one uses the generated power from the magnet hitting the coil and a very short burst of input energy to fire the motor.

The trick is in the timing and configuration. He used a South on South setup. As the south magnet comes into the south face of the coil (If you were looking on a scope) you get rise in voltage. As the curve rises you fire a small burst. This give the opening to ground.
The South on South produces a small spike that is counter the positive voltage you put in the coil. It would show up on the scope pointing down.
That energy released to the ground actually can add charge on the ground side.
The biggest thing you have to worry about is the timing. Your timing magnets should not allow the coil fire for no more than about 1/3 the distance of the magnet its pushing away.

And it will not keep the battery charged it will just take forever to run the battery down.

Hope thats what you needed.
