Wind Turbine Axial Flux Alternators
Wind Turbine Axial Flux Alternators
Learn more about the design of an axial flux alternator - used in wind turbines and hyrdo power
windIn our article
Wind Turbine Alternator Basics we looked at how electricity is generated in a
wind turbine as magnets rotate past fixed coils of copper wire.
The basic concepts behind axial flux alternator design are very simple, and it is well within the capabilities of any DIY enthusiast to put together their own alternator. To find out more we recommend you read the concise (free) guide to
axial flux alternator basic principles linked to at the bottom of this article.
The guide covers
neodymium magnets explaining clearly how
magnetic fields behave, and how magnetic energy can be
concentrated to maximise the electricity generation capability of an alternator.
It then looks at how coils of
enamelled magnet wire can be positioned and connected to generate
three phase AC electricity. By matching the coils (number, size, number of coils etc) to the magnets (number, size, shape), and matching the finished alternator to the
propeller (diameter) a reliable and efficient
wind turbine generator can be constructed.
