MAC112B-1-GD-4-C/130-A-2/WA610XX/S018

The MAC112B-1-GD-4-C/130-A-2/WA610XX/S018 is a high-performance AC Servo Motor from Bosch Rexroth Indramat’s reputable MAC AC Servo Motors series, designed for demanding industrial applications. This MAC Permanent Magnet Motor features a robust Motor Size 112 and a compact Motor Length B, ensuring a balanced form factor for integration into existing assemblies. With a nominal supply of 230 V AC and a dedicated power connector on Side A, this model delivers reliable energy transfer under continuous operation. Its precision construction supports both incremental and absolute encoder configurations coupled with tacho feedback, providing exceptional positional stability and dynamic response. Weighing 36 kg, the motor maintains structural rigidity while minimizing vibration-driven wear over long service intervals.

Technical excellence defines the MAC112B-1-GD-4-C/130-A-2/WA610XX/S018, starting with its Continuous torque at standstill of 16 (29)^5) Nm and a Continuous current rating of 41 (75)^5) A to sustain high static loads without thermal degradation. The unit’s Maximum peak of pulse current of 223 A supports rapid acceleration profiles, while the Nominal motor speed of 3000 min^-1 meets throughput requirements for high-speed positioning tasks. Internally, a Rotor moment of inertia of 120 x 10^-4 kgm^2 optimizes dynamic response, balancing torque density against control stability. Electrical characteristics advance performance further with a Torque constant at 20 °C of 0.430 Nm/A, coupled with a low Windings resistance at 20 °C of 0.090 Ω and a Windings inductance of 1.2 mH for fine current control and minimal phase lag. The Thermal time constant of 90 (60)^5) min ensures the motor can operate at peak loads under intermittent duty cycles without risking thermal overload.

Operationally, the motor employs a Surface Cooled design that leverages axial airflow to dissipate heat efficiently, enhancing continuous duty life and reliability. A specially engineered heavy-duty blocking brake secures the rotor position when power is removed, preventing unwanted drift in critical hold applications. The combination of high torque constant, robust blocking brake, and low rotor inertia yields smooth, precise starts and stops, reducing mechanical stress on linked machine components. Thanks to its Mass of 36 kg and optimized construction, the motor exhibits minimal vibration, thus extending bearing life and lowering maintenance intervals across diverse industrial environments.

Integration of the MAC112B-1-GD-4-C/130-A-2/WA610XX/S018 is facilitated by its standardized mounting interface and encoder-ready shaft, ensuring compatibility with a wide range of drive controllers and feedback systems. Its streamlined form factor and Motor Size 112 footprint allow straightforward replacement or upgrade within existing installations. Ideal for precision robotics, high-speed balancing machines, and advanced automation platforms, this servo motor delivers the reliability and performance engineers demand. With its comprehensive specification set and rugged industrial design, the MAC112B series motor stands as a versatile solution for complex motion control challenges.
