Greartisan DC 5V 0.5RPM Turbo Worm Geared Motor High Torque Turbine Worm Gear Box Reduction Motor 6mm Shaft JSX5300-370

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.

Worked great for my diy project. I used some rubber foam to reduce buzzing sound for super quiet operation in my project. Before had a 10rpm and it was ok, but I wanted a bit more speed and still good torque. So I got the120 rpm and a pwm motor speed controller.

Looks nice and feels solid, however, the gears are so tight, the motor doesn't have enough power to turn them. It just gets super hot and would probably just burn up if I left it. I took it apart and the gears turn fine and the motor works as expected, however, it doesn't work as it's supposed to. I even removed the very sticky lube that came with it and replaced it with a high quality lube, but it still didn't work. Note that by design, you won't be able to turn it by hand, but if you happened to get a good one, it should turn with power applied. Mine doesn't though.

Unbelievable quality and craftsmanship. Was not expecting this at all. When I opened the box I thought I received the wrong item or there was a mix up. Have now applied this to a complete and totally new project that was never thought I could do because there were no motor/gear assemblies that could do the project and have it to this small of a size which is what I wanted to do. Also weight was an issue. NOT ANYMORE!!!Initially I had tried to come up with the right gear assembly that would work for such a highly torched drive but by the time I was done it was far too big so I gave up and placed it on the back burner. It's the worm drive that is the answer here. I am completely satisfied with what I have received and I will be doing so much more business with this company. Awesome job guys. Great workmanship.Can not say enough good about this entire product...

I have several of these along with the associated "flange" that can be slid onto the shaft. I use this combination as small rotating photo tables powered by a variable voltage DC power supply. The beauty of these motors is their high gear ratios make them operate stably at even a fraction of their rated 12 volts. Lower voltage makes them rotate substantially slower, so you essentially have a variable speed turn table. The only downside is the connection tabs are so fragile you have to retrofit a connector to the motor as your first order of business. Even at a lower voltage they only draw a fraction of an amp so you could probably get variable speed with just a rheostat.
