MAC112C-0-HD-4-C/130-A-1/WI531LX/S005

The Bosch Rexroth Indramat MAC112C-0-HD-4-C/130-A-1/WI531LX/S005 is a high-performance permanent magnet AC servo motor in the MAC AC Servo Motors series, engineered for precision motion control in demanding industrial environments. This MAC Permanent Magnet Motor delivers robust torque and rapid response with its compact Motor Size 112 and Motor Length C configuration. Designed for reliability, the unit features a standard incremental encoder interface and an integrated blocking brake assembly. Its rugged construction and optimized magnetic circuit make it suitable for continuous operation under varying load conditions. The motor’s Cooling Type Natural Convection ensures passive temperature regulation without auxiliary fans, reducing maintenance requirements.

The detailed technical specifications of the MAC112C-0-HD-4-C/130-A-1/WI531LX/S005 reflect its sophisticated electrical design. It maintains a continuous current at standstill of 41 (67) A and a continuous torque at standstill of 27.0 (44.0) Nm, ensuring reliable start-up under load. The motor supports a maximum peak of pulse current of 195 A for short-duration torque surges. At nominal conditions, it sustains a nominal motor speed of 2000 min^-1 with a torque constant of 0.730 Nm/A @ 20°C. The rotor’s inertia moment of 170 x 10^-4 Kgm^2 provides a balance between mechanical stability and dynamic acceleration. Thermal management is defined by a thermal time constant of 100 (75) min, facilitating accurate thermal modeling in system design. The windings exhibit a resistance of 0.150 ohm @ 20°C and an inductance of 2.5 mH, supporting predictable current dynamics.

Operational performance is enhanced by the motor’s mass of 48 kg, which contributes to mechanical rigidity and vibration damping in mounted assemblies. Its natural convection cooling allows continuous torque delivery without airflow constraints, and the blocking brake holds shafts securely when de-energized. The high peak current capability accommodates rapid acceleration profiles, while the balanced rotor inertia ensures smooth transitions during speed changes. Built for durability, the motor withstands industrial duty cycles with minimal thermal drift and extends service intervals. The integrated encoder interface provides precise feedback for closed-loop control applications.

System integration of the MAC112C-0-HD-4-C/130-A-1/WI531LX/S005 is facilitated by standard mounting dimensions and industry-standard signal protocols, enabling seamless incorporation into multi-axis servo drives and CNC controllers. Its compact footprint and natural convection cooling simplify cabinet designs for factory automation, robotics, and material handling systems. The combination of high torque density, reliable braking, and low maintenance makes this motor ideal for packaging machinery, assembly lines, and precision positioning applications where consistent performance is critical.
