Hello guys, I have the next problem. For a proyect I have, I need to assemble a DC motor with an encoder to obtain useful information like movement speed, acceleration and position of two wheels, and I don't know how to assemble those. I'm using two DC gear motors and two encoders as are displayed below (12[V], 30 [RPM] and torque between 6.3[kg/cm] and 14[kg/cm]), which are OK because my project consists in a robotic platform that has to load a maximum of 15[kg] distributed on two wheels and an industrial caster one. There is a possibility I could assemble the DC gear motors with the encoders I have? or maybe I'd better buy an AB024 rotative encoder for arduino instead the encoders I have as an alternative way?

Thanks in advance.

The encoder doesn't have to be attached to the motor itself, it can be attached to the linkage somewhere or the wheel itself. Sometimes adding a rubber wheel and a spring to the encoder shaft is all it takes to get acute feedback. Similar to how an rpm meter is used.
It might be better (more reliable) to use an "absolute" rather than an incremental encoder for robotic projects like this.
