Re: [Electronics_101] Small motor searches - looking for sources....
- how about the motor from the radiator fan? They are usually 12V, 10A at max rpm, and pretty well built.I have used one of this as a servo some time ago, and it has a lot of torque.sorin----- Original Message -----From: Chuck MerjaSent: Thursday, June 29, 2006 6:05 PMSubject: RE: [Electronics_101] Small motor searches - looking for sources....
How about automobile salvage yard theyd have window motors, if you decide theyd work.

The small motor I was planning to use for my spindle drive just
isn't got enough oomph to drive the spindle cartridge I made. As
typical of me, I built the spindle a bit "over-kill" and it's a bit
stiff, but certainly not incorrectly built - just a bit stiff for
that little toy motor.
So, now the hunt is on for a replacement motor. I can get some
automotive power window motors for about $20.00. They are 12 Volt,
3.5 ~ 12 Amp at stall. They come with a worm-drive type gear box
but it looks easy enough to pull the motor from that. I would
suspect these motors to have some pretty good torque and power.
I have a number of AC motors lying around here that might work. But
I have no idea how to make an AC motor variable speed like I was
doing for the DC motors.
I check a couple of my favorite surplus websites -
www.surpluscenter. com, AllElectronics, etc. didn't see anything
there that said "I am the motor you are look for".
Any suggestions as to where to look or even where I might slavage a
suitable motor? The motor does have to be small, about 3" diameter,
4 1/2" long, give or take a bit.
Any an all suggestions would certainly be appreciated (as always) !!
