Greartisan DC 12V 100RPM Turbo Worm Geared Motor High Torque Turbine Worm Gear Box Reduction Motor 6mm Shaft JSX69-370

These little motors are surprisingly powerful, and fairly easy to work with. I used one for my chicken coop door, to open and close it using ESPHome, and have no problems with the motor.The drive shaft is keyed nicely, allowing a spool to fit on it securely, and the amount of power you can get out of it is startling. My coop door isn't very heavy, and testing this thing on a vice with a power supply attached I was able to lift a 5kg weight, although the motor protested loudly.Only caveat I have is that the tabs on the back of the motor are a bit finicky about accepting solder, but some wax flux and patience got a good connection eventually

I like to tinker. I purchased this motor 4 months ago and just got around to using it to make an automatic live insect feeder. I just finished test running the 3D printed turntable for 24 hours and it is working better than my expectations.

Great price

I bought the 15 RPM worm drive motors but I tested the speed I found that all were rotating at just over 12 RPM. I checked my voltage supply to make sure it was correct and found that it was good. Either the motors are labeled wrong or someone did not calculate the gear ratios correctly. Other than that, I have had no problems.

it met my expectations in my exmerimentation

I purchased two of these for a project I was working on that needs 150-250 rpm with a decent amount of torque. The ones I received max out at around 10 RPM. I can’t find a way to contact them for support and I’ve passed my return window.

Bought this little Greartisan 12v 25 RPM as well as a larger BringSmart 12 volt 16 RPM worm gear 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. Will probably donate this little one to my son for an Arduino project or something like that. I'm forced to give it stars before I used it so I will give it five stars and then come back and adjust accordingly if necessary.

The media could not be loaded. It works and is as described but it is a lot louder than I expected. It makes a low humming-grinding sound that can be heard many feet away in a quiet room.
