R911249780
The R911249780 (MDD112C-N-015-N2L-130PA0), manufactured by Bosch Rexroth Indramat, is an AC servo motor under the MDD series. Renowned for its high operating reliability, it thrives in applications such as packaging machines, robotics, and grinding mechanisms due to its synchronous motor designs and the advanced level of synchronism it attains. The MDD motor's reliability lies in its temperature sensor-integrated windings for overload prevention and maintenance-free operation, thanks to a brushless design and permanently lubricated bearings. The R911249780 (MDD112C-N-015-N2L-130PA0) comes without an optional blocking brake but does support digital servo feedback. The motor housing is compatible with both natural convection and surface cooling methods.
Performance parameters vary according to the chosen cooling method. With surface cooling, the motor delivers a higher output torque of 43.2 Nm and current of 34.3 Amps at standstill, unlike the 28 Nm torque and 22.2 Amps current registered with natural convection. The R911249780 (MDD112C-N-015-N2L-130PA0) motor has a maximum torque of 97.2 Nm and 82.6 Amps current, with a nominal speed of 1500 RPM. It flaunts a DIN 6885-1 standard keyway main shaft, an IP65-rated housing, and a 130mm motor centering diameter. Weighing 48 kilograms, it operates optimally at ambient temperatures of 0 to 45 degrees Celsius.
