R911247504
The Bosch Rexroth Indramat R911247504 (MDD093B-N-030-N2L-110GB0) is a servomotor designed for cost-effective automation systems. It is part of the MDD product range and is specifically suited to rapid applications such as roller feeds for pressing machines, nibbling machines, and tool changing devices. The MDD motors are permanent magnet synchronous motors featuring electronic commutation. The use of rare-earth materials in the construction of permanent magnets ensures the motor’s low inertia. The R911247504 (MDD093B-N-030-N2L-110GB0) motor is known for its high operational reliability due to maintenance-free operation and built-in temperature monitoring sensors in the motor windings. It has a nominal speed of 3000 RPM and features a standard housing suited for natural convection or surface cooling.
The R911247504 (MDD093B-N-030-N2L-110GB0) supports digital servo feedback and its continuous torque and current measurements vary depending on the cooling method used – with natural convection at 14.5 Nm and 24.1 Amps, and with surface cooling at 20 Nm and 33.2 Amps. The motor's rotor moment of inertia is 0.00029 kg m2 and its windings' inductance is 4.4 millihenry. Depending on the cooling method, the thermal time constant varies between 45 to 50 minutes. This servomotor, which weighs 16.5 kilograms, is supplied without a blocking brake, with a power socket located on side B. It offers IP65 protection rating and features a centering diameter of 110 millimeters with a plain main motor shaft.
