45kwh dc motor diy Edit
- http://www.reuk.co.uk/DIY-2kW-Wind-Turbine.htm The generator was designed with a 24 Volt three phase stator (3 coils each phase) and two rotors with twelve 46x36x12mm rectangular shaped NdFeB (Neodymium) magnets each. The hub and rotor assembly was built out of scrap 1995 BMW front strut with a pair of brake discs. See http://elektritsaabtasuta.blogspot.com/2010_03_14_archive.html

https://www.youtube.com/watch?v=bHzt74CE0fg 1.7mil views The resin used is epoxy, which can be cost effectively obtained for R30,000 per 200litre drum. See Lathe. It would probably be cheaper to build a DIY commercial metal caged alternator as epoxy at R150/kg imported is expensive. Bought in 5liter volumes around R500 and it becomes unfeasible. A planetary gearbox on windturbine output shaft allows for a much smaller alternator, saving on expensive neodium magnets.
