Product Description
Independently wound generators are a good choice for replacement generators and DIY wind turbines. This generator has the benefit of CVT-like design: If the field magnets are more strongly energized, the motor will produce more power at a given RPM. The field magnets can be wired in series for a self-exciting unit, or separately energized with either DC or AC to respectively produce DC or AC current. The field magnets' requirements depend on your intended RPM and you should be willing to experiment with variable field strengths because this will determine your power output and torque loading. An additional benefit of a unit with field magnets is that it exhibits no cogging when the magnets are not energized. See photos for detailed measurements.The generator has a construction much like a standard dc generator- except instead of rare-earth magnets, it has field magnets which need to be electrically excited. Therefore, the generator will put out DC if fields are excited with DC, and likewise it will put out AC if fields are excited with AC. As far as voltage goes, the generator should put out 12-24v depending on the RPM and how strongly you excite the field magnets. The fields should draw something like 10 percent of the amperage that the generator will put out, and the resistance of the field magnets will depend on your intended RPM. Given you excite the field magnets with grid-frequency AC, you will be outputting grid-frequency AC so you will have a wide variety of transformers available to use from anything like a 12v battery charger or microwave.
