I thought I would start this thread because I believe there are folks out there who may have insight, knowledge or experience they could share with the rest of us to get us to where we want to be. I am not a particularly intelligent individual when it comes to electronics. I am just stubborn as hell and will butt my head against a wall until I find a way through it. But I have figured out a few things, borrowed a few things from others, and spent a lot of time and money researching this stuff. There are things I know how to do, but do not yet understand the WHY of it, and that bothers me.
Let me put before you a premise, and let's go from there. What if you had a home made generator with magnets on the rotor and iron cores in the coils, and there was no magnetic attraction between the iron cores and the magnets on the rotors, so your rotor would basically freewheel when spun by hand, but you STILL got to take advantage of the induced field from the magnets in the wire wrapped around the core of the coil. Would that be of some value?
Now what if you could then add a load to that generator and it caused the motor running it to speed up, drawing fewer amps. Would THAT be of even greater benefit to you?
Step #1 I can show you how to do. In fact, I've made sure that understanding how to do this does not vanish from the face of the earth if something happens to me, but I'm not sharing it yet because....Matt is building a prototype right now that he is sending me so I can get the coils wound. I built a small two coil model, and it worked, so we are putting something together we can share with others. When it is done, when we have tested it, when we KNOW it works, then you'll see it here.
So now, let's talk about coils speeding up under load. I have seen coils speed up under load. I have seen it with air core coils and with solid core coils. I have seen it with "regular cores" made out of welding rod, and with U shaped coils. What do all these coils that speed up under load have in common??? Come on, you can tell me, right? Can't you make EVERY coil speed up under load?
Matt built a two coil prototype motor with iron cores and high impedance coils and it sped up under load. Citfta ran a rotor through the pump motor coils and got them to BARELY speed up under load, and I ran my rotor but could NOT get them to speed up under load. Why? Same coil, but different rotors at different speeds with different magnets. Angus Wangus shows U shaped coils (like the pump motor coils) speeding up under load. BIG time. I replicated his experiment and mine worked like a charm with a U shaped piece of iron rod, so I thought the pump motor coils would be a natural. They are the right shape, and already wound. No joy so far.
So my question is folks, what EXACTLY do we know about how to get a coil to speed up under load? Is it the resistance? Is it impedance (Thaine Heinz says so, and I have seen it work with high impedance coils, but also with coils that are NOT high impedance.) Is it the size of the magnets? The number of magnets per second (or some ratio like that) If we KNOW the answer, then we should be able to make EVERY coil we build speed up under load. What IS the magic formula? I have four different coils that will speed up under load right now, and I need to set my test stand back up to start gathering some data. I hope I don't have to do it alone, because I will, but it would be nice if ALL of us benefited from this information. We're all in this together, right?
