Three Phase Basics

Get an understanding of three phase wiring in wind turbine alternators

An excellent resource for anyone interested in understanding why the majority of wind turbine generators (1) are wired in three phases should take a look at this excellent article on Three Phase Basics (2) from WindStuffNow.com. Find out about the differences between wiring in Delta or Star configuration (3), and calculate how many RPM (4) your turbine will need to spin at in order to start charging your battery bank (5).

Another useful polyphase electricity article can be found at the Standford website: The polyphase motor/generator. (6)
