Encoder Metal Gearmotor 12V DC Low Speed 60 RPM Gear Motor with Encoder for Arduino and 3D Printers

My oscilloscope showed the encoder output to be noisy and not at all a square wave. A and B outputs were 90 degrees out of phase, as they should be, but the signal had no sharp edges so it was useless.

No da las rpm qué prometen, es muy baja su velocidad incluso sin la caja reductora, le realice varias pruebas con su caja reductora y sin ella, el puro motor sin caja reductora no alcanza buena velocidad, parece más un motor de 100 rpm qué de 300 rpm.

Good motor, works as expected. I use it for my small robot. Encoder works fine too. Company provides a code for Arduino in C++, which handles encoder data and controls motor with motor class. This code contains PID controller lines, but I am not using this. I modified this code for my needs, but I did not change a core part about encoder which works fine. Finally: this is a good motor. It can be used to drive small robot. Maybe RPM is high for this, but it is acceptable for small carts.

All good

I've had little luck with cheap DC motors with encoders in the past but I have to say this one is exceptionally high quality for what it costs. Encoder works no problem, and they are very quiet when compared to similar DC motors I've bought in the past.
