MAC112B-3-GD-2-C/130-A-1/S005

The Bosch Rexroth Indramat MAC112B-3-GD-2-C/130-A-1/S005 is a precision-engineered member of the MAC AC Servo Motors series, designed for rigorous industrial servo applications. This AC Servo Motor features a compact Motor Size 112 and a robust Motor Length B construction, delivering a Nominal motor speed of 3000 min^-1 for consistent rotational performance. The motor’s electromagnetic design incorporates a Torque constant at 20 degrees C of 0.430 Nm/A and a Windings resistance at 20 degrees C of 0.090 ohm to maximize torque yield while maintaining thermal stability. Electrical characteristics include a Windings inductance of 1.2 mH that supports rapid current dynamics and a Continuous current at standstill of 41 (75)^5) A to sustain low-speed torque without thermal overload. Early integration is facilitated through a standard power connector on Side A, while the built-in B-encoder tacho feedback system ensures precise position and speed monitoring in real time.

Performance characteristics of the MAC112B model highlight its capacity for demanding dynamic loads. The motor delivers a Continuous torque at standstill of 16 (29)^5) for extended low-speed holding, and can withstand a Maximum peak of pulse current of 223 A for brief high-torque demands. Its Rotor moment of inertia of 120 x 10^-4 Kgm^2 is finely balanced for rapid acceleration and deceleration, minimizing overshoot in motion profiles. Thermal management benefits from a Thermal time constant of 90 (60)^5) min that ensures gradual temperature rise under continuous operation, while the Surface Cooled configuration dissipates heat effectively across the housing. The motor’s electrical-to-mechanical response is further refined by the 0.090 ohm winding resistance and 1.2 mH inductance, enabling tight current control and swift torque generation.

Built for long-term reliability and seamless system integration, the MAC112B-3-GD-2-C/130-A-1/S005 weighs a compact Mass of 36 kg without compromising structural integrity. The integrated Standard blocking brake provides 45 Nm of holding torque, securing the load in power-off or emergency conditions. Its robust design supports operation across a range of ambient environments, with a proven surface-cooled housing that maintains performance under continuous duty cycles. The combination of high-resolution tacho feedback and standardized mounting dimensions simplifies installation with Bosch Rexroth analogue drives and modern CNC controllers. Ideal for machine tools, packaging equipment, and automated assembly lines, this motor excels in applications requiring precision, safety, and dependable high-torque operation.
