DC Geared Motor Recommendation?

JohnBot115

Hi,
·
Just wondering if anyone had a recommendation for a low RPM, high torque motor, or place I can find a motor with the following characteristics:
·
RPM around 400 to 1000
Torque around 30 inch-pounds or equivalent
24 volts max, 12 better
·
I’ve checked many of the usual suspects: all electronics, and other popular sites. Nothing yet. Or at least, nothing I’m sure of.
·
Thanks.

Have you looked here, they have a reasonable range.

Another option is this

http://www.andymark.biz/am-0518.html, with the CIM motor its designed for. I have used the motor and the larger version of this gearbox without problem.

Try car windscreen wiper motors. I have standardised on the Ford Mondeo on all my builds.
These are high quality motors, which you can pick up on eBay for about 5 pounds, or 10 US$

Rough spec...

With approx 12v slow speed draws from 1.79A thru 2.2A
fast speed draws from 3.23A thru 3.5A

12 twisted axis poles so no cogging

Fast is 3180 RPM ~ 50 RPM out of gearbox
Slow is 2640 RPM ~ 42 RPM out of gearbox

Gearbox is a 63:1 reduction

Easy to add a tachometer to these things, just bounce some Infra Red off the amature.
