MAC112B-0-LD-4-C/130-B-1/WA610XX

The Bosch Rexroth Indramat MAC112B-0-LD-4-C/130-B-1/WA610XX unit is a high-performance servo actuator in the MAC AC Servo Motors series designed for precision motion applications. It features a 112 motor size and B length type with a total motor length of 385 mm, delivering a nominal speed of 2,000 rpm and continuous torque at standstill of 17.5 Nm. Built for reliability, this MAC Permanent Magnet Motor integrates both a B-type encoder and a tachometer to ensure repeatable positioning and real-time speed feedback. The drive interface includes a power connector on Side B and a standard blocking brake, making it compatible with DCS and KDS drive controllers. With an IP65 enclosure rating, it is dust-tight and protected against water jets, ensuring robust performance in harsh industrial environments.

Detailed electrical characteristics define the MAC112B-0-LD-4-C/130-B-1/WA610XX servo motor’s capabilities. The continuous current at standstill is 26.3 A, while the maximum peak of pulse current reaches 130 A for demanding acceleration profiles. Its torque constant at 20 °C is 0.74 Nm/A, and the windings exhibit an inductance of 3.5 mH and a resistance of 0.26 Ω at 20 °C. The rotor moment of inertia is 120 × 10^-4 kg·m², optimized to balance dynamic response and load inertia. Thermal management is achieved via natural convection and a thermal time constant of 90 min, allowing stable operation under sustained loads. The motor mass of 36 kg supports heavy-duty installations while maintaining structural integrity.

Operational features and performance parameters are engineered for consistency and longevity. The standard electromagnetic brake produces a holding torque of 45 Nm, ensuring secure stoppage and positional retention during power interruptions. Orientation options B05 and B14, conforming to DIN 42950 standards, permit flexible installation in diverse machine layouts. The fully enclosed housing, rated IP65, protects internal components from particulate and moisture ingress, and the absence of brushes eliminates maintenance associated with commutator wear. Lifetime-lubricated bearings and integrated thermoswitches prevent overheating, while the permanent magnet design reduces heat generation, supporting high torque density at standstill and dynamic operation.

System integration is streamlined with compatibility for Bosch Rexroth DCS and KDS controllers, enabling advanced features such as auto-tuning and real-time diagnostics. The combination of absolute encoder and tachometer outputs simplifies feedback wiring and improves redundancy in position and speed control loops. Cooling by natural convection minimizes the need for external chillers or airflow management, making the motor suitable for confined or sealed enclosures. This servo motor is ideal for packaging machines, assembly robots, CNC machining centers, and other precision automation systems where high torque, rapid response, and environmental resilience are essential.
