Encoder Metal Gearmotor 12V DC High Speed 300RPM Gear Motor with Encoder for Arduino and 3D Printers

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.

I needed it for a computer control project and it worked nicely.

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.

El producto llegó muy rápido y es de buena calidad

Initially it wouldn't turn - the magnet in the encoder had slipped away from the sensor and wedged against the plastic shell. Eventual figured it out and got it working

Pretty robust shell and wiring allows to be installed with little concerned about tight spaces or being to rough while handling it with tools.

This motor is well built, powerful, and well documented.

Used this motor in a small project, pretty cool it has a built in encoder for a feedback system

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.
