MAC112C-1-ED-2-C/180-B-1/S012

The MAC112C-1-ED-2-C/180-B-1/S012 is a high-performance member of the MAC AC Servo Motors family, designed and manufactured by Bosch Rexroth Indramat to deliver precise motion control in demanding industrial settings. This MAC Permanent Magnet Motor features a robust brushless design and surface cooled configuration with an axial blower to maintain optimal operating temperature. It integrates a C encoder for accurate position feedback and includes a standard blocking brake for safe, fail-safe stopping. The motor’s compact profile and efficient thermal management make it an excellent choice for continuous and variable-speed applications.

With a Nominal Motor Speed of 3000 RPM and a Continuous Torque at Standstill of 24 Nm, this servo motor provides steady performance under load. It sustains a Continuous Current at Standstill of 57.0 A and can handle a Maximum peak of Pulse Current of 312 A, ensuring rapid torque delivery during acceleration. The Torque Constant of 0.470 Nm/A and a Windings Resistance of 0.060 Ohm contribute to its energy-efficient operation, while the Windings Inductance of 1.0 mH allows for fast current dynamics. The motor’s Thermal Time Constant of 100 min, combined with its IP 65 Protection, ensures reliable operation in harsh environments. With a Mass of 48 kg, a Motor Size of 112, and a Motor Length of C, this compact unit balances power density and stability.

Operationally, the motor’s advanced stator design guarantees smooth torque output and reduced cogging, supporting precise positioning and vibration-free motion. The flange’s standardized configuration simplifies mechanical integration and alignment in machine assemblies. An integrated shaft sealing at the flange prevents ingress of liquids, enhancing durability in washdown or high-humidity applications. The maintenance-free, brushless construction minimizes downtime and extends service intervals, while the blocking brake adds an extra layer of safety during power loss conditions.

Integration of the MAC112C-1-ED-2-C/180-B-1/S012 into existing automation systems is straightforward thanks to its standardized interface and compatibility with Bosch Rexroth drive controllers. Its high torque-to-inertia ratio and reliable thermal performance make it ideal for robotics, packaging machinery, material handling, and CNC tooling applications. The motor’s robust protection and feedback capabilities ensure consistent performance in both new installations and retrofit projects, delivering precise, repeatable motion control across a wide range of industrial processes.
