Excellent combination of DC Motor with strong Gearbox and Magnetic Encoder.
This would be a perfect solution for your next SERVO project.
For only few $ you will get a complete servo motor. Just add a servo amplifier or build it yourself.
This is a low cost solution for any hobby or school project.
The gearmotor is rated for 24VDC and it comes with 12 pulse/revolution (motor revolution -see below) magnetic encoder.
The output speed reaches 144 rpm but because the encoder is attached to the motor shaft and not to the output gearbox shaft the resulting output from encoder is 300 pulse/revolution giving quite good resolution and may be used for precise positioning.
Motor has cobined connector for motor wires and encoder. The connector is 6-pin: 2 wires for motor, 3 wires for encoder, 1 empty.
Motor wires: Red +, Black -
Encoder wires: Yellow - Sig Output; Blue - Gnd; Orange - +5V

Data Sheet for Gearmotor is available from our website http://www.interinar.com/public_docs/DME44_3.pdf
Page 1 shows parameters and torque curves for motor alone. Do not use it unless motor will be detached from the gearbox. On the same page you will see connections for the magnetic sensor (encoder).
Page 2 shows parameters for motor WITH attached gearbox. This are the parameters you should use for you calculations. Refer to DME44B series and do not use DME44S series, which applies to a different motor. The gearbox you are interested in is type 6DG however the motor is shipped with 6H which has larger diameter of output shaft, increased to 8mm. Look for Gear ratio 25:1 for exact parameters.
