Looking for a Small High Torque 12V DC Motor

[dbassman]

I'm hoping someone here might be able to help me… I'm looking for a High Torque 12V DC Motor. I've been unable to find one that meets advertised torque values.

Important considerations:

#1. 12V DC
#2. 120 RPM or greater
#3. Body diameter approximately 25mm
#4. Shaft diameter 4mm
#5. Torque (Sustained) >4kgf-cm; (Peak) >8kgf-cm
 
Any help would be greatly appreciated!

It sounds like you have already tried some motors with these specs, what did not work?

First off, I have to admit I don't know a lot about this, but I'm trying to help my partner find a more powerful motor for our needs.

We got a couple different ones from China off ebay & they did not have the power of our current motor with lesser specs...  We're currently using this motor , but would like one that's a little stronger (more torque). Were also afraid with our current motor that the planetary gear pins will begin to fracture.

The other issue we're having is trying to find them at a reasonable cost, trying to stay around the $15-$30 range. If we have to spend more, we will… Just trying not to!

Any help would be greatly appreciated!

superdroid robots has a good selection of geared BDC motors you could check out their selection.

i would be very cautious of any ebay china items. i definitely wouldn't trust the engineering data they provide ... but it seems like you figured this out
