Firstly great Forum, didn't expect this much knowledge and wisdom here in SA
I got a box full of Cylinder Magnets, not Neodymium, the "Normal" stuff. Its just sitting in my Garage and begging to be used. Im not too sure about the strengh, it should be OK as it can still pull the colour out of my Television.
Its about 20mm in Diameter, and about 40mm in Length. So I was thinking about an alternative design and I would love to get some feedback on my ideas.
First some images...
I could use either of the designs, in the first I would use 40 Magnets on the Rotor and 36 Stator Coils.
In the second I could use 10 Magnets per Rotor on 4 Rotors and 9 Coils per Stator on 3 Stators.
I would prefer to use the latter as the design would not take up too much space.
Im not hoping for much, somewhere in the 300W Range, @ 24VDC.
I got a nice 3 blade, 5 ft, composite, variable pitch aircraft prop to use ass well.
I aim to wire up the rig in 6 or 9 phases.
I would also like to build some controller that will link the some phases in Serial (More V, less A) @ low wind speed & Parallel (More A, less V) in high wind conditions.
Yay or Nay?
Could someone also please comment on the following? I think I'm right, just wanna make sure...
Windings - More windings per coil = Output more V, less A, Less windings = Output less V, more A.
Magnets - Stronger Magnets = Better Output.
Rotor to Stator - The smaller the Air gap, the better the output.
Rotor - Constructed from Aluminium would not affect output.
Stator - Giving each coil a Ferrite core should increase efficiency.
Awaiting your input...
