R911276484
The R911276484 (MDD112D-N-020-N2M-180PB0) is a highly advanced servo motor produced by Bosch Rexroth Indramat. This model doesn't include a blocking brake, however, brakes with holding torque ratings of 14, 40, or 60 Nm can be added upon request. This motor is designed to operate optimally at ambient temperatures of 0 to 45 degrees Celsius and altitudes up to 1000 meters. It can be stored in environments with temperatures ranging between -20 and 80 degrees Celsius. With an IP65 protection category, RAL 9005 black housing coat, and insulation class of F, these motors are constructed to provide reliable service for longer periods. The R911276484 (MDD112D-N-020-N2M-180PB0) motor boasts a nominal speed of 2000 RPM.
The usable speed of this motor is determined by the torque requirements of the particular application. The continuous torque and current at standstill are quantified as 38 Nm and 43.8 Amps respectively, and the peak equivalents are 134.8 Nm and 166.4 Amps. The rotor has a moment of inertia of 0.023 kg m2, and the shaft features a keyway. This 59-kilogram unit is designed for cooling through natural convection or surface cooling. It also supports digital servo feedback with an integrated multi-turn absolute encoder, has a centering diameter of 180 millimeters and the power connector is located on the right side of the housing. Qualified personnel should oversee the motor's installation.
