Greartisan DC 12V 30RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox

Good value, good product. I did return the first one because it was not running smoothly. I use a 5 amp variable output power supply I bought at Amazon. I was surprised at the reduced voltage torque output for a motor that runs at less than 5 amps. As more load is applied the speed remains high. It runs slowly at three volts. At six volts the rpm is about half the rated speed, but the torque is more than half the rated torque, or so it seems to me. At full voltage and a decent torque output, they don't overheat. I used them to make a linear sander for making wooden gears, using a pair of linear rails. Without these motors, I couldn't have done it so easily and inexpensively.

I used this motor for my work pumpkin contest and it worked perfectly! It was easy to use and quiet, and ran consistently when turned on.

These are solid little motors and I love that you can buy them in all different gear ratios. I am using mine in an animated art sculpture. It slowly spins a fairly large armature made of PVC pipes. The piece will be outside. In calm winds the motor seems to handle the load just fine. The question is if the internal gears (don't know if they are metal or plastic) will hold up when stronger breezes try to oppose the motion of the motor. Right now I really like these.

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.

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.

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.

If you need to replace a ZGB37RG this motor works but packaging is quite foolish, because it is so short the terminals get bent, I have bought two and they each had this issue!

Excelente

Rotation juste, moteur décommander assez puissant pour sa grosseur ,silencieux

Tutto ok come da descrizione.

Era exactamente lo que necesitaba, quedó muy satisfecho.

I used it on my lifesize R2D2 to rotate the dome. Works perfectly, wired it up no problem.

Top, drehen sauber und ohne große Geräusche.
