MAC112D-2-HD-4-C/130-B-0/WI520LV/S005

The Bosch Rexroth Indramat MAC112D-2-HD-4-C/130-B-0/WI520LV/S005 servo motor, part of the MAC AC Servo Motors series, delivers robust performance for precision automation and heavy-duty industrial tasks. Manufactured by Bosch Rexroth Indramat, this high-torque, low-voltage design features the specialized WI520LV winding to optimize efficiency at reduced voltage levels. With a nominal speed tailored to 1500 min-1, the motor combines endurance and responsiveness for demanding applications. The unit’s surface-cooled construction and rugged IP65-rated housing ensure reliable operation in environments subject to dust and moisture.

Detailed electrical and mechanical specifications underscore the MAC112D’s engineering excellence. The Torque Constant of 1.010 Nm/A ensures predictable force output, while the Rotor Moment of Inertia of 230 x 10^-4 kg·m² provides stability during rapid load changes. At standstill, the motor draws Standstill Current of 42.0 A and develops Standstill Torque of 38.0 Nm, supporting precise position holding. Winding characteristics include a Windings Resistance of 0.176 Ohm and an inductance of 3.2 mH, facilitating fast current control. The motor’s Maximum Peak Pulse Current rating of 195 A allows handling of transient loads without degradation.

Operational features emphasize consistent high-performance delivery under variable loads. The Thermal Time Constant of 120 min reflects the design’s capacity to sustain elevated torque over extended cycles, minimizing thermal stress. A compact footprint—defined by Motor Size 112 and Motor Length D—balances power density with ease of installation. At a mass of 59 kg, the unit’s solid ferrous construction resists vibration and mechanical shock. The surface-cooled configuration maintains optimal operating temperatures, ensuring that torque and speed characteristics remain within tight tolerances throughout the duty cycle.

System integration is streamlined through compatibility with Bosch Rexroth Indramat drive controllers and industry-standard feedback devices. The MAC112D series supports advanced features such as field-oriented control, torque ripple minimization, and real-time diagnostic monitoring for predictive maintenance. Targeted applications include automated material handling, CNC machining, packaging lines, and robotics, where the combination of precision, durability, and low-voltage efficiency delivers measurable improvements in throughput and energy consumption. The MAC112D-2-HD-4 variant embodies the reliability required for modern high-demand manufacturing environments.
