How do they know the characteristics of the turbine you are going to put on?
exactly, they don't know the rotation speed of the blades or if it's going to be driven by water, air or a motor of some kind. and to get back to the small diameter wire; based on the voltages they are quoting, if they are planning to develope any current the wires will fry very quickly
I think the magnets must all be facing with the same pole outward, then the metal is acting like the opposite pole.
I worry about alt companies that try to tell you power vs wind speed. How do they know the characteristics of the turbine you are going to put on?
Hi, in all fairness the PMA I posted seems to be from a different company. Thanks for the information. It seems a lot of companies are offering products before they are ready.
Lets find renewable solutions to reduce energy cost
Here is somebody that is not too happy with the 7 magnet PMA.
Hi, the power conversion circuit would solve the problem. It would take a high voltage with low current and converts it to a lower voltage with higher current at the output. Heavier wire would only be required after the power conversion circuit to the battery. I can configure the belt drive transmission to a max ratio of 1 to 7. They do not provide output to RPM information but other suppliers do. I am searching for a alternative to the F&P that would reduce labor.
Hi, after a suitable solution for the power conversion circuit is found. It appears a number of off the shelve PMA may be suitable to use with a VAWT. Because I am able to fabricate the belt drive transmission, I do not believe reaching a high RPM at a average wind speed would be a problem, if the blades are large enough.
I found this seven magnet PMA on eBay, I am puzzled by the 7 magnet configuration. Comments welcome
