MAC112C-0-KD-4-C/130-B-1/WI520LV/S021

The MAC112C-0-KD-4-C/130-B-1/WI520LV/S021 from Bosch Rexroth Indramat is a high-performance member of the MAC AC Servo Motors series. This AC Servo Motor features a robust Motor Size of 112 and a compact Motor Length designated as C, ensuring compatibility with a wide range of industrial drives. Engineered with a Cooling Type of natural convection, it maintains optimal thermal stability in demanding environments. The integrated incremental encoder and standard blocking brake augment its suitability for precision positioning and safety-critical applications. Designed for versatile mounting through its centering diameter, this servo motor delivers reliable operation and straightforward installation.

With a Continuous current at standstill rating of 31.0 A (up to 49.0 A peak), this motor provides substantial holding capacity when idle. It generates a Continuous torque at standstill of 28.0 Nm (up to 44.0 Nm peak) to maintain loads under power-off conditions. The motor achieves a Nominal motor speed of 1500 min^-1, which is well matched to typical automation cycle requirements. Electrical performance is optimized through a Torque constant at 20 degrees C of 1.000 Nm/A and a Windings inductance of 4.5 mH, delivering responsive torque control. The Windings resistance at 20 degrees C of 0.270 ohm facilitates efficient current flow, minimizing heat generation during prolonged operation.

Operational reliability is further enhanced by the motor’s Thermal time constant of 100 minutes (75 minutes optional), allowing for sustained overloads with minimal risk of overheating. The rugged construction yields a Mass of 48 kg, providing mechanical stability and vibration damping in heavy-duty applications. With a Maximum peak of pulse current capability of 141 A, the motor can handle rapid acceleration demands for high-dynamic positioning. The Rotor moment of inertia of 170 x 10^-4 kgm^2 ensures smooth motion profiles and precise settling times. Together with the standard blocking brake offering up to 45 Nm of braking torque, these features support reliable standstill holding and safety locking under load.

This servo motor integrates seamlessly into decentralized drive architectures and CNC systems. Its standardized flange and centering diameter simplify alignment and reduce assembly time in modular production lines. The combination of high torque density, natural convection cooling, and robust encoder feedback makes it ideal for packaging machinery, conveyor systems, and robotic axes. With its flexible mounting options, integrated brake, and industrial-grade components, the MAC112C-0-KD-4-C/130-B-1/WI520LV/S021 delivers enduring performance across a spectrum of automation and motion control applications.
