These DC motors are equipped with gear box and encoder. It uses 2 phase or 2 stations (quadrature) incremental encoders to detect the rate of the motor, direction of rotation and the length it has travelled.
Encoder feedback data allows you to control your motor quickness and path efficiently. DC motors with encoder feed back transmission usually called DC servo motors.
DC motors with encoder have got many applications in robots, robot arm, CNC machine and many other applications that require accurate control of velocity, direction and position. You can control your engine using microcontroller or arduino.
