12V 16rpm DC Worm Gear Motor 70kg.cm High Torque Turbine Electric Gearbox Motor Self-Locking Reversed Mini Engine Geared Motor for DIY Robot Door Lock Curtain Machine (12V 16rpm)

My husband said they worked great.

This thing has tons of torque probably gor to get a 45 rpm one this ome is 16 but has no problem. Using it on a homemade milling machine for my y axis and it hold the head exactly where it stopped

Used it for a motorized waterfowl decoy. It has a LOT of torque for its size. It is much smaller than I anticipated, but is good quality and simple to wire up. Very little noise under load as well.

Bought this BringSmart 12 volt 16 RPM worm gear motor as well as a Greartisan 12v 25 RPM motor. I wanted to put a picture of them side by side so you could get an idea of what you're paying for. The little one was around $15 and the bigger one was around $30. That's of April 2021. I am planning to build an outdoor motorized 12-ft projection screen. I believe the Bringsmart will have enough torque for the project. I feel it is well worth the extra $15. It's easily twice the size and has wired leads as well as mounting holes on both the front and back. However if you're doing something smaller you might like the space that the Greartisan saves. The little one is roughly 3 in and the bigger one is roughly 4 and 1/2 in long. I haven't used it yet but I'm forced to give it a review. So I'll give it five stars and come back and adjust it if I have any problems.

Very easy to install once you take your Trim off the slide-out. Works perfect.
