BRINGSMART JGY-370 12V 6rpm DC Worm Gear Motor Self-Lock Electric Motor

Great little gear motor, seems to be of good machined quality and materials. For the 6 rpm motor at 12VDC, I measured the stall torque using the test setup shown (accounting for the torque contributed by the weight of the pliers), and found the motor torque to be 32.3 in-lb (37.2 kg-cm). My only gripe is the lack of data sheets, especially since it appears that, in addition to gear ratio the motors also differ between rpm models.... so you can't presume that torque will be inversely proportional to rpm when comparing motors of different rpms. Attached is info obtained from an eBay listing for what I believe to be the same product, but I can't confirm so use at your own risk. Despite the many sellers of this design, I think they're all made by, or licensed from, the same Chinese manufacturer.

Quiet with plenty of torque.

todo exelente

When I got it it was locked up. I took it apart and fixed it. It works fine now but I shouldn't have had to fix it. It should have worked right out of the box

This motor showed up not working. And yes I am an electrician and this messed up a customers custom order. This has made me look bad in front of my customers. I will be going with another vender for now on.

Works, it is just very slow.

Out of box hooked to slice. It buzzes but does not turn

Haven’t used yet because project got deprioritized.

it rotates the solar cell into the sun.
