The Bosch Rexroth Indramat MAC112C-0-HD-3-C/130-A-0 servo motor from the MAC AC Servo Motors series offers a high-performance solution for precision motion control in demanding industrial environments. With a nominal speed of 2000 min^-1 and a continuous torque of 27.0 Nm, this dynamic servo motor delivers both speed and power for applications requiring rapid acceleration and consistent torque output. The motor’s torque constant at 20 °C of 0.750 Nm/A and maximum peak of pulse current of 195 A ensure efficient energy conversion and exceptional responsiveness under transient loads. Specifically engineered by Bosch Rexroth Indramat, the MAC112C-0-HD-3-C/130-A-0 balances dynamic performance with structural robustness, making it ideal for high-precision automation. Its optimized winding parameters, including a windings resistance at 20 °C of 0.150 Ohm and a winding inductance of 2.5 mH, reduce heat generation while maintaining electrical efficiency.

The detailed technical specifications of this servo motor underline its suitability for sophisticated control systems. The centering diameter of 130 mm and motor size of 112 provide a compact footprint without compromising mechanical stability. Its rotor moment of inertia of 170 x 10^-4 kgm² allows for rapid changes in speed and direction, supporting agile motion profiles. The thermal time constant of 100 min indicates robust thermal management, ensuring prolonged operation under heavy duty cycles. At a mass of 48 Kg, the motor remains appreciably lighter than equivalent power classes, simplifying integration into machine frames. The motor length C designation corresponds to a medium-profile housing that accommodates natural cooling through natural convection, eliminating the need for forced-air systems.

Operational performance of the MAC112C-0-HD-3-C/130-A-0 is characterized by its ability to sustain high dynamic loads while preserving precision. The combination of continuous torque at standstill and a peak pulse current capacity ensures that the motor can swiftly overcome load inertia and maintain position control. The nominal speed rating supports coordinated multi-axis movements in robotic and CNC systems, while the / torque constant and winding parameters facilitate tight current-to-torque correlation for seamless servo tuning. Additionally, the natural convection cooling mechanism prevents thermal overload, leveraging the thermal time constant to manage heat dissipation effectively. The sturdy mechanical design resists deformation and vibration, thereby extending the operational lifespan of both the motor and its coupling components.

System integration is straightforward, with the MAC112C-0-HD-3-C/130-A-0 compatible with standard INDRAMAT servo drives and feedback controllers. Its AC Servo Motor MAC architecture aligns with industry-standard communication protocols and safety functions, enabling easy incorporation into existing automation platforms. Target applications include precision handling in assembly lines, dynamic positioning in packaging machinery, and high-speed rotary indexing tables.
