TheBackShed.com - F&P Re-Wire: "F&P Stator Rewiring
From factory the Fisher & Paykel stator is wired into one large star winding, producing 3 phase AC when used as a generator*. If we were to use this on our windmill the output voltage would range from 0 to 300 volts unloaded, and up to 2-3 amps maximum loaded, not a very usable range for charging batteries.
The standard stators have either a string of 14 or 12 poles for each phase. 3 phases, means 42 or 36 poles total, depending on what model stator you have. We are going to rewire the stator into shorter strings to reduce the voltage, and then connect these strings in parallel to increase the current.
* Technically its an ALTERNATOR, but the term GENERATOR is more commonly used.
There are 2 F&P Smartdrive combinations commonly used for our windmill alternators, the old 42 pole stator, and the new 36 pole stator."
