Greartisan DC 12V 20RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox

A+++

I've purchased several of these in different speeds, and I'll keep buying these whenever I have new projects. Excellent durability. I've noticed the low-speed, high-torque options are quieter than the higher-speed options. They're not silent, but can be reasonably quiet.

I built a filament respooler that called for a 100RPM motor. (not pastamatic, the original one) I bought the recommended motor but it was loud and to be honest, a bit slow for my tastes. I found this motor which is faster and quite a bit quieter. (by no means quieter, just a lot quieter than the other motor I used) I am guessing the noise is from the gear box. I can use full speed on my motor controller but it is a bit too fast. I can slow it way down and it still works. At a certain point, slow is just off. (pretty close to the off position) I recommend this over the motor listed on printables because it is quieter, faster and much less expensive.

This low speed motor (60rpm) has more gearbox noise than I was expecting, which is still tolerable though a bit annoying. Because the motor is geared down to such a low speed, the torque is enormous making it almost un-stoppable. But the gearbox losses make the no-load current pretty high. I have had it running under light load for about 4 hours now - It does get slightly warm, the current and speed have not varied, so it seems like good value.

Works just fine. I needed a DC motor for my DIY project and I see no issue's with this motor. up to 15 kg torque.

Very good quality no issues at all

The size of the motor was perfect to create a rotation device for a roaster. Low noise, just the right amount of power as I wanted to spin slow. It worked as intended.

it met my expectations for my experimentation
