If you are making a Hard Drive Wind Generator you will need to wire up a bunch of coils. This tutorial video from The Geek Group goes over some 3 Phase Rectifier Basics. See this page for more details.
“For three-phase AC, six diodes are used. Typically there are three pairs of diodes, each pair, though, is not the same kind of double diode that would be used for a full wave single-phase rectifier. Instead the pairs are in series (anode to cathode). Typically, commercially available double diodes have four terminals so the user can configure them as single-phase split supply use, for half a bridge, or for three-phase use.”
