The MDD112D-N-020-N2L-180GA0 is a digital servo motor manufactured by Bosch Rexroth with a standard casing design. The motor possesses dual cooling approaches; natural convection and surface cooling. As surface cooling, generated by a fan or blower, is more efficient in heat dissipation, the motor can yield a higher output, with continuous torque at standstill measuring at 57 Nm and the continuous current at 43.8 Amps. By comparison, with natural convection it's 38 Nm and 65.8 Amps respectively. The MDD112D-N-020-N2L-180GA0 does not have a holding brake; it weighs 59 kg and has a maximum potential torque of 134.8 Nm. Other key features include a peak motor current of 166.4 Amps, a torque constant at 20 degrees Celsius of 0.87 Nm/A, a winding resistance at 20 degrees Celsius of 0.18 Ohms and a winding inductivity of 2.7 millihenry. The motor operates optimally between 0 and 45 degrees Celsius and can be safely stored between -20 to 80 degrees Celsius. It has an installation elevation cap at 1000 meters above sea level, operates at a rated speed of 2000 RPM, and has a plain shaft. The power connection is housed on side A. The 180mm centering diameter motor also comes with digital servo feedback and is finished in black prime coat (RAL 9005).
