Hello, I am still new to the wind power scene. I am trying to find out more information about the washer motors used in the windmills. What is the AC voltage output of the F&P in stock configuration as well as some of the rewired configs? And what is the amperage? What are the rpms that give the AC volts?

Hi;
Good question!
They are built to power a washing machine. Here in the states a washer will typically have a 1/3 HP.some may have 1/2hp. 300-500 watts. and operate on 120 volts AC 60 Cycle
and require a current of 2.6- 4.2 ampere's.
The F&P is built in New Zealand Maybe elsewhere also, Is wired for 240-250 volts AC 50 cycle.
The current needed for the same job with this motor would be 1/2 the amount in the first example. This assumes that the motors have identical efficiency.
The wiring in this F&P is sized for higher voltage and can not handle the amperage needed for lower voltage systems.
I To would like to see a data tag on the F&P as the company built it. Time has proven that I am blind to the Obvious, some of the above may be True?

The motor its self is not run at that frequency. Its driven by a microprocessor controller.

Depends on the stator.
100S has 44 turns of 1mm wire 42 poles.
80S has 115 turns of 0.8mm wire 42 poles
60S has 170 turns of 0.6mm wire 42 poles
60DC has 170 turns of 0.6mm wire 36 poles
Rewiring as follows (plenty of other configs not here BTW)
Voltage AC is rarely talked about here as its useless "WILD" A/C as the frequency changes alot with rpm
20KHZ at speed.
Amps depend on the system voltage and the re-wire you chose.
EG at 600rpm a 100S in delta may make 800W into 48V battery at 60V with cap doublers which is 13A
the same stator into 24V would make about 13A but it would only do 400W unless it was re-configured to 2X7C, in which case it may put out 26A.
It doesnt suit 12V very well so may only make 26A at 12V which is "only" 270W.
These are pretty much all educated guesses based on Peoples experiences, SMARTDRIVES, has got 600W into 12V which is 40A+ out of a smartdrive, this is by no means gospel as moving 40A is very tough -short cable runs, heatsinks etc etc etc.
My advice -choose a system voltage you are going to work with. -Most efficient (for the smartdrive) and with the widest range of equipment to suit 24V is probably the go.
48V doesnt really suit the rewires perfectly BUT, line losses as 1/2 what they are at 24V and we have grid tied inverters that need 48V systems.
If you choose 12V -I recommend against.
all your kit needs to be rated for some serious AMPS and you'll find gets expensive in BIG everything to keep losses down.
Thats my bit.
If you are interested I have one of each remaining in stock but postage to the states is an absolute killer at about twice what the F&P's are worth.
Your best bet is randys workshop, get a 36pole 60DS. run it as 7x2C delta into 24V, lash out and get the newest magnet hub from www.ecinnovation.co.nz
They have 20% more magnet than the previous hence ~20% more grunt..
This solution should do 600W into 24V no worries with reasonable startup speeds etc.Edited by KarlJ 2010-02-17Luck favours the well prepared

Thanks ROBB, I should have guessed that.(old man Out of touch).
I'm starting to realize why there is much concern which model is being discussed on a post. and Thanks to KarlJ I now know why the 100s is so desirable.
KARLJ;
A very informative post, I realize this is not exact spec's but a overview of likely performance from the different models.
This should help a lot of people make up their mind which one suits their needs. Time has proven that I am blind to the Obvious, some of the above may be True?

I'm Biased as I run two of them on my mill
Phill didnt have enough wind for both but still rus one 100S in delta for the big end of wind scale and the 80S in 2x7C star for the light stuff.
The master os all is Gordon who has cracked 890W out of a 100S in delta with NO NEO's.
Some I believe have cracked the 1KW but using neos.Edited by KarlJ 2010-02-17Luck favours the well prepared

The key to big numbers is high rpm and good winds, and matching to the load.
Gordon.
PS:- big numbers only happen some of the time.
PS: edit- I don't have an F&P any more.Edited by GWatPE 2010-02-17become more energy aware
