Robodo REL_45 12V Dc Gear, Geared Motor 500 Rpm with Clamp for Robotics

I've used it to spin mirror ball and it spins perfectly well and the speed is good too. I use it for almost 9-10 hours and it works great. I would say go for it.Just a reminder, motor makes a lot of noise. However, as this price point, you can ignore the noise. In a busy room, you wont hear it though.

Not 300 rpm just 10 or 20 rpm maximumTorque is goodNo return possible only replacement...Bad luc.. my cash is waste..

Good rpm & high torque, Not properly stopped by hand on 6v-12v 5amp. but if I give less amp it stopped by hand. It takes 540mA on load.On this price good item.

worked for me

I bought it for a project of my kid. But the motor didn't worked for 30 minutes. Even if you are keeping the motor working for a minute or two. The condition of motor when received was looking like its used one, but after checking just for one time I decided to use it for the project. That was mistake.Amazon should monitor their vendors and product feedback from customers. I would recommend to buy such product from local vendors to avoid last minute failure.

So as the title says, I've now purchased (and tested) a total of 4 of these now. They work super well running 24/7 at least for the past few days (on 12v, 2amp power supplies).I have noticed though that the sound varies drastically from motor to motor. While a couple are fairly quite, the others are slightly noisy to really noise, having rattling or just loud motor sounds. It's about 50/50 with the ones I got (2 quiet, 2 quite loud). I kind of wish they were all as quiet as the quieter ones. One in particular is very loud. Not as loud as a paper shredder or anything, but louder than the others for sure.

The motor are the best motor in low price Amazon best motor and the packaging is good 👍

The RPM remains same irrespective of the voltage provided. Only the Torque changes based in the voltage. So in order to get 6kg-cm torque u need to provide 12V DC power.
