Extractor motor

[Will]

What size motor should I use to convert my Kelly 3 frame tangential extractor? I'll be extracting deep frames. Name brands and locations will be appreciated.
Thanks,
Will

I would have guessed a ceiling fan motor wouldn't be powerfull enough but it seems to work for this guy
you can certainly find one cheap at a thrift store

there are a number of prior threads considering this question. I use a very old gear drive drill motor chucked directly to the reel shaft. the drill is anchored to the extractor cross member with a bit of light angle iron. I acquired this drill from a local flea market (although I have yet t locate the fleas). I utilize a bench top voltage regulator (very heavy duty rheostat) to increase or decrease the speed. this last item was acquired from an electronic technician friend of mine. total cost of the two

I have a Garbage Disposal Motor that I salvaged from my kitchen remodel. After tinkering around a bit, I think I can make it work on my extractor. But after talking to a Maintenance Guy (who works with this kind of stuff), he said I need a VFD to soft start the motor, and slow down the RPM's of the motor. But these VFD's seem to be very expensive (like $200), and not readily available at my local hardware store. So what is this Rheostat Tecumseh speaks of? Is that just an old term for the VFD? or is it a cheaper alternative? Does anyone know where I could get (or scavenge off) a part for this type of application?

Thanks, Jon D.

the problem is that most motors you find around for cheap are AC motors that have a fixed rpm that is controled by the frequency of the juice you put into it (wall current is 60 Hz) most of em turn way to fast. The ceiling fan motor I mentioned is wound differently so it spins at a more reasonable speed
an even better solution is what tecumseh mentions which is a variable speed motor
unfortunately variable speed motors are DC and not as easy to find
one good source like tecumseh mentions is a variable speed electric drill
I've seen a homemade extractor that was just powered with such a drill which you held in your hand to drive it
no mounting
simple, worked great, the only problem is you couldn't walk away while it was working

a half inch variable speed drill probably turn at 600 rpms max. the speed you are likely trying to achieve is more like 350 rmps. with a heavy duty drill there is a second 'handle' (a 3/4 inch pipe that screws into the drill motor body opposite the tradional handle) which as a drill gives you the ability to manipulte the heavy drill with both hands. it is via this 'handle' that I attach the drill to the piece of light angle iron. drill or burn a whole in the angle iron at the right height and anchor the drill with a short 3/4 inch pipe nipple and two conduit electrical nuts.

john d ask:

tecumseh adds:
I would be guessing but likely yes. my electronic gizmo friend has two or three setting on his work bench but he mainly use them to vary the speed on a couple of regular fans. I don't think they serve any real function in regards to his electronic business. another quess is that a heavy duty wall plug type rheostat might work just as well.

Check with your local garage door company and tell them you are interested in a DC motor off one of the take down residential openers they replace.

They will run variable speed with no problem and also are 1/2 HP for the most part.

They should give them to you for little or nothing.

surplus center, lincoln nebrask typically has a lot of dc gear motors and motor controllers that would be an excellent choice to power up a small extractor. their web address is www.surpluscenter.com. (http://www.surpluscenter.com.) ask them to send you a catalog.

I have acquired product from them in the past for various projects and their product and service has always been excellent.

tecumseh adds a bit more detail:
my electronic geek friend call the article that I acquired from him a ver-arc (sounds like, but likely spelled incorrectly). I did note that suplus center advertised a heavy duty 25 watt rheostat in one of their catalogs (very cheap) and my electronic geek friends though that this would quite likely work in an application with a geared drill motor.
