Proffessional 1 Kw Generator (Prototype)
This is a generator that the team and I at ICONIX Research & Development designed for a client. It is a 1 Kw generator to spec out a prototype for a wind turbine. This uses propriety technology that we developed and is currently under NDA, so I can't tell you any more about that that. (I am going to put a picture on here as soon as I can get it watermarked for security reasons.) You can check it out on the companies web site here.
This suspicious looking guy is actually a permanent magnet radial flux generator. It may be a little crude, but I made this completely by hand with the exception of the engineers best friend, the Dremel. It has two sets of neodymium N45 mags and 12 iron cores. This is a standard 3 phase permanent magnet generator. The cores are made of hand cut steel lamination (it took a long time). All the cores are connected to a single core piece, the flux will travel from the coil to perimeter of the housing to the next coil, unfortunately due to space I was unable to fit enough material in, causing a low saturation level. I made the rotor by making a form in which to embed the magnets in fiberglass and resin.
The way I have it wired, 3 coils wired in series, then the two rows wired also in series. It produces 25 V at 100 RPM, due to the saturation mentioned earlier the most current i was able to get out has been 7 AMPS short circuit.
This is also the occasion where I learned that it is possible to repair broken magnets, I’ll cover how I did that else where on this site.
I'll post more soon.
