Low RPM Supplies

What you want is a low RPM Permanent Magnent Alternator. You can run 3 phase AC over a long distance using normal outdoor extension chord. Then convert it to DC when you get it to your house. If you want to tie into the House AC power, you will need a grid tie inverter, so that the phase will match. Grid tie inverters also have a failsafe in case the power goes out.

Check out this site for supplies. They have everything from parts (for the DIYer) to complete systems.

Grid Tie

I am not an expert, but I have done some research and have put in Solar Panels, Wind Generator, along with large battery bank and a High Amp Altenator on my sailboat. That gives me some experience.

With 3 phase AC, you can use an ordinary 3 wire outdoor extension cord from your generator to your bridge rectifier. AC will transmit over a long distance with 14 ga extension cord. DC will need welders cable to go the same distance. Your bridge rectifier should be close to your batteries and grid tie inverter while your generator could be outside somewhere.

You would have a multiple of three coils to go 3 phase. Either 3, or 6, or 9, or 12, etc. EX: If you have nine coils, 1,4,7 are tied together, 2,5,8 are tied together, and 3,6,9 are tied together.

As far as your picture of your coil and magnet setup, you have the spacing right where north is on one side of the coil and south in on the other side of the coil (assuming N,S,N,S,N,S setup on your magnets). You can add more magnets and shorten the width of the coils. Basically, maximize the number of magnets and coils which should maximize the current.

You want to convert to DC before using a grid tie inverter. The ones on the market, both sense and match the sine wave coming in from the power company. A commercial grid tie inverter is essential so there is no "Out of Phase" on your power. You want to match the sine wave coming in. The grid tie inverters are required to automatically shut off when there is a power failure, so you will not transmit AC while the power companies are working on the lines. You need to pick a grid tie that matches the voltage and watts for your system. There are a lot of grid tie inverters on the market.

If you go to batteries first, a good option on an inverter is a low voltage shutoff. This way, you will only add AC to the grid as long as the battery is up. Some grid tie inverters plug in directly to an AC house plug. Some inverters require a certified electrician to add it to the circuit breaker box.

Coils and Magnets

I think it is important to understand electron direction when a magnet passes over a coil. The attached picture should demonstrate this.

As a result (assuming you want three phase), I think you should wind all your coils in the same direction but the size and spacing of the coils are critical so that the magnetic fields line up.

Then you would need to decide if you want a Star or Delta config.
