Re: Cheap drive motors? [TANKS]

["Gregory Pwneror" <sockless67-at-gmail.com>]

i cant say as i dont know the torque, but i think they might work, they are cheap so you can probebly just use themand see how they go, if they start smoking get some bigger ones or more motors, like you suggested; 2 motors a side.

try these instead DCM-231 (from the same site). 

they have a longer drive shaft and it is slotted so it fits perfectly into a Powerwheels gear box.

 

While i am not building an RC tank per se, I am building a tank type robotic lawnmower and using the powerwheels gear boxes.  Since the weight will be significantly less, I am not too worried about the plastic gearing.

I bought a couple of these motors a while back:

http://www.allelectronics.com/cgi-bin/item/DCM-267/400/DC_MOTOR,_3-24_VDC_.html

3-24V range, $3.50 per.

I didnt buy them for the tank. they were going to be used in a 1/144 battleship when I got around to building it.

I have since reviewed the specs and even saw a website for a guy who upgraded his Powerwheels with them.

I figure that a 3:1 gearing will give 5-6 mph at 12V.

I am not good with specs when it comes to electric motors though.

Any suggestions?

If worse comes to worse, would running 4 of them (powering the "idler" in addition to the drive sprocket) make a difference?

Thanks,
