Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

  GWatPE said   "It has a DC field of 100 volts, DC armature of 90 volts, armature amps 7, base rpm of 1750, windings 12340. All this info is on the plate on the motor."

BTW if converting to permanent mags......
Field of 100V at 1750rpm.... you would be lucky to get that after install of permanent mags and you will be running much lower rpms thus Id reckon shes good for 30V and Perhaps 2A = a whopping 60W.........

All a guess of course but neos and machining are expensive and F&P's/LG permanent mag motor/alternators are basically free and good for 500+watts.....

Thanks for all your input. I just thought it might be a good project to play with and see what I could make the motor do. My only cost would be the magnets because I would do all the machining work myself. But heck I was looking at some of the links last night and I have found more things I can play with that are smaller and might produce a better result, so I think I might just go that way.
I have 25 of the n42 1x2x1/2 magnets on order plus a 50+ lbs roll of magnet wire so I should have plenty to play with when it gets here.
Again thanks

Dont feel bad Bub & I have a collection of motors we thought would but didn't do what we thought they would so I guess I can go fishing this summer as I have lots of boat anchors! hehehe.
Karl
Where can I get one of those F&P's for free??
Ive been thinking more on them lately
We don't have a hi wind average speed and don't expect to totaly electrify the house with a wind mill but tie it in with solar panels and one helps the other on off days
We are doing what we can on a low budget..

With the fright cost from Australia to the US making a purchase none feasible.
What would be a good way to check for one of these F & P type motors at the local salvage yard??
I was at the local yard the other day and there was a machine there that looked to be fairly new.
I tipped it over for a look see and the machine seemed to be lighter than normal to me and it was all boxed in. I would have to take tools to remove a cover to look.
The owner wasn't there at the time so I didnt pursue it.
I may go back next week and take a look.
They usually have a number of machines there.
How is the pump driven off one of those machines?

F&P has a separate pump A/C (induction type i think)

if you manage to source something in direct drive (most of them LG etc are F&P stolen designs) so you might be in business.

Do they normally run washing machines on 110V or 240V?
I know some of you have 240V and 110V.

Perhaps 110V motors are better candidates for conversion to windmills as the voltage is a closer match.

The washing machines I had any experience with are 120V
But the F & P clones could be 240 v
The electric dryers run on 240 v.
What is the common failure on these machines with the F & p type motors?
Is there much of a possibility If I get one out of the salvage yard it would have a bad motor?
Probably stick my head down there and smell for burnt wires?
Looks to me like they should wash forever?
Maybe some of the others here in the usa will get on board here and help us out with some info??
Thank You
Isaiah

The motor itself would only die if it was sitting in water for a long long time, but rotor has drain holes tp prevent this.

I have only ever found 1 that was not worth using (out of 100's of them)

You do see plenty with cracks in the stator plastic but apparently this is no issue.

I am aware that the hub needs painting to prevent UV degradation but not sure about the stator, dont think anyone paints the plastic (but if they do it cant hurt)

And if its recommended, someone can sing out now and i'll do mine too!

The main thing that fails in the F&P is the control panel or rarely seals and bearings on the shaft.

Which is kinda good the panels fail (unless you own one) as we dont use that part anyway.

Once you rip the tin sheet cover off the underside of the machine you will see the motor clearly.

Undo the plastic hand nut in the centre of the hub and pull the hub off then you will see the exposed stator.

Happy hunting.

Pete.
