How to build a WIND TURBINE Axial flux alternator windmill plans 8 foot and 4 foot diameter machines © Hugh Piggott -May 2003 How to build a wind generator - the axial flux alternator windmill plans - May 2003 version © Hugh Piggott the results are quick for a one-off product. Moulded fibreglass blades are usually better for batch production. Wooden blades will last for many years. Introduction Blades These plans describe how to build two sizes of machine. The diameter of the larger wind-rotor is 8 feet [2.4 m]. The smaller machine has 4' diameter [1.2 m]. The diameter is the width of the circular area swept by the blades. page 2 DIAMETER Furling system The plans include a description of how to construct a furling tail for the larger machine. This tail prevents overload in high winds. This type of furling system has been in use on Scoraig for decades and has passed the test of time. Units The energy produced by wind turbines depends on the swept area more than it does on the alternator maximum output. Alternator The plans describe how to build a permanent magnet alternator. The alternator can be wired for 12, 24 or 48-volt battery charging. Essentially this choice only affects the size of wire and the number of turns per coil. But the tower wiring for the 12-volt version will be much heavier than the others. And the stator for the small machine is different in thickness. The alternator design is integrated into a simple tower-top mounting arrangement (called a 'yaw bearing')....
