MAC112C-0-HD-3-C/130-B-0/S021

The Bosch Rexroth Indramat MAC112C-0-HD-3-C/130-B-0/S021 is part of the MAC AC Servo Motors series, featuring a robust AC Servo Motor design optimized for industrial motion control. With a nominal motor speed of 2000 min^-1 and a torque constant at 20 degrees C of 0.730 Nm/A, this motor delivers precise rotational performance for automation systems. The unit’s cooling type via natural convection ensures consistent temperature management during continuous operation, making it ideal for high-duty-cycle applications in manufacturing and processing environments.

This motor exhibits a continuous current at standstill of 41 A (peak 67 A) and a continuous torque at standstill of 27.0 Nm (peak 44.0 Nm), demonstrating substantial starting power for load-intensive tasks. The maximum peak of pulse current reaches 195 A, enabling brief torque surges without compromising motor integrity. With a rotor moment of inertia of 170 x 10^-4 Kgm^2, the design balances inertia and responsiveness, while a windings inductance of 2.5 mH and windings resistance at 20 degrees C of 0.150 ohm optimize electrical efficiency and dynamic response. The thermal time constant of 100 minutes supports stable thermal behavior under sustained loads.

Constructed with a motor size of 112 and motor length of C, the MAC112C-0-HD-3-C/130-B-0/S021 integrates a centering diameter of 130 mm for precise coupling to flanges and gearboxes, enhancing alignment and reducing mechanical stress. The absence of a blocking brake and the inclusion of a power connector on Side B streamline system integration and maintenance. Weighing 48 kg, the motor’s durable build withstands harsh industrial conditions, while efficient natural convection cooling reduces auxiliary power consumption. Employing proven induction technology, this servo motor offers reliable, low-maintenance performance, delivering consistent power transmission and improved uptime in automated production lines.
