Back to Basics

In order to produce electricity in what we call a generator you must turn the rotor that has magnets on it past the coils. There are variations on how that is put together, but that is the basic idea. There are three basic problems you have to overcome to build a successful motor/generator combination. So letís look at them one at a time.

The first experiment you need to try is simply to turn a rotor with magnets on it and see what your cost in watts over time will be. Then add a coil and see what the increase in watts over time will be. You must add at LEAST one more coil to even begin to do the math, and two or three more would help, but here is what you are going to see.

There is an upward curve in amp draw and a downward curve in rpm of the prime mover as it is affected by the iron in the cores that the rotor magnets travel past in their rotation. That downward curve has a relationship to the downward curve in production of the coils.

Then start doing some math. How many coils can you add before the amp draw exceeds what the prime mover is rated for. What will your production be at that point? Will it exceed the cost of running your motor at high amps? If it did, everybody would just run their generator with an electric motor.

So this is your first problem. How to eliminate the increased amp draw caused by the coils. Because the more coils you add the greater the amp draw. Luckily there are TWO solutions to this issue. One is mechanical and the other is electrical. The mechanical solution is magnetic neutralization which I have talked about until I am blue in the face. Simply explained, it means when a rotor magnet is attracted to the iron in the coil core, ANOTHER magnet in the rotor is aligned in repulsion to a magnet on the stater counteracting that attraction. The electrical solution is to LET the rotor magnet be attracted to the iron core, acting as a generator as the magnet is approaching, but once the two are aligned, fire the coil as a motor coil to push the magnet on past. Then once again allow it to act as a generator coil as the rotor magnet moves away. Switching and proper timing become critical.

The second issue is that when the generator is put under load, this is reflected back to the prime mover causing increased amp draw, a decrease in rpms, reduced output from the generator and, if you have enough coils on your generator, your motor will draw so many amps you will be able to roast marshmallows over the flames. The solution is to wind coils as we have shown that produce NO reaction in the prime mover. This has been explained in detail in several threads now. Wound in parallel but connected is series. The thing to remember is that RVERY coil has a speed at which it has NO self induction. So either keep increasing the speed until you are traveling fast enough for your coil, or wind you coil correctly.

Last problem is the heat generated by the coil cores. Change core material, figure out a way to transfer or dissipate the heat. Water works.

Thatís it
