while it sounds complicated, its actually a VERY simple design not counting the coils and magnets there is roughly 60 parts, and 15-18 of those will be blades and 30-36 will be blade mounts lol. and all the parts are the same so it goes together like a set of legos. the lenz2 design is what im basing my blades on, however, im modifying them slightly to work in close proximity to other blades. so its more of an aerofoil design. i didn't c the standard "u" shape as being entirely efficient.
the glory of the way i have this drawn up in cad is that if i want to change blade designs, i can disassemble the blades from the plates, and replace them with a different mount and blade design. the same with the coils. they are mounted to a plate induvidually, so if i want to try different windings, or whatnot, i remove the plate break the solder connections and replace to coils.
the maglev part of it, has to stay...if for no other reason than i have already bought 2 very large neo 50s lol. really, if you could see the design you would be like...oh, duh lol thats easy, its just a lot of machining repetative parts, and bolting it together. today, i have been doing cost analysis, and seeing that im doing all the design and machining myself, that just leaves parts, i should be able to get all the aluminum and steel i need for around 500 bucks. id like to do carbon fiber blades (just for aesthetics) but i dont have an oven, so aluminum will work for now.
the magnets are gonna hurt a bit. i already have $300 in the 2 i got, and i now need (at current count and design) 90 smaller magnets for the PMA. (30 for each layer, one magnet will actually work 2 coils, more efficient). each of those needs to be 1x2x1/2 [n 2 inches s] the coils will be 1.5 inch cubes so a 1 inch tall magnet should be fine...
im planning on spending at least 750 dollars on magnets, then 200 for the magnet wire.
IF!!, i can get the EE class to set me up with a inverter, (since it IS a school project lol) then maybe i can save the money there, and buy a good inverter later. i not, then tack on another 2 grand or more. im thinking this thing is gonna make lots of power, i would like to see 3kw, (the base deign for this makes 5 at 18 mph with large deflectrs) but i will probably only hit that number in 20mph winds, and that doesnt happen often here will probably be a constant 10. we will see when i build it huh?
anyways, not counting the inverter, ill have roughly 2 grand in it. if it works the way i want it to, that will be 2 grand well well spent.
i have seen a 5200W generator, but it needs a low power source to activate it, and must turn at 600 rpm to achieve rated power. so i would need a gearbox. and i would no longer have a "0 friction design." not to mention i dont know how to wire for the "low power source"
i think i've though it through fairly well. i will post some pics of the design when i get it laid out to the point you can tell whats going on. like i said, the hold up was just figuring out what base plate design, but im pretty set on my layered approach now.
ok enough rambling lol..thanks for all you guys input and ill get that book.
