R911284778
The Bosch Rexroth Indramat R911284778 (MDD112B-N-030-N2M-130PA3) is a high-quality AC servo motor, designed to work with digital drive controllers in precision applications such as robotics, textile, packaging & printing machinery, and grinding machines. With a nominal speed of 3000 RPM, this motor is particularly suitable for tasks that require extreme synchronism. It offers a continuous torque at standstill of 17.5 Nm with a continuous current capacity of 28 Amps. The peak torque capability is 64.5 Nm and a peak current of 110 Amps. This product has a moment of inertia of the motor rotor of 0.0012 kg m2 and a torque constant of 0.62 Nm/A at 20 degrees Celsius. The winding resistance is 0.25 Ohms at the same temperature.
The R911284778 (MDD112B-N-030-N2M-130PA3) motor features a winding inductance of 3.1 millihenry, and a thermal time constant of 90 minutes. A specialized blocking brake, with a holding torque of 60 Nm, is designed to prevent shaft rotation at startup. This brake releases upon receipt of a 24 Volts DC signal. This motor comes with a natural cooling standard housing and supports digital servo feedback with an integrated multiturn absolute encoder. The power connection is located on side A of the housing. The motor is centering at a diameter of 130 millimeters and comes with a keyway-fitted output shaft. Weighing at 36 kilograms, this motor ensures robust and reliable operation.
