MAC112D-1-HD-3-C/130-A-0

The MAC112D-1-HD-3-C/130-A-0 is a high-performance module in the MAC AC Servo Motors series by Bosch Rexroth Indramat. This AC Servo Motor features a robust Motor Size of 112 and a compact Motor Length designated as D. It is equipped with a power connector on Side A for streamlined installation and includes an integrated D encoder for precise position feedback. The unit is delivered without a blocking brake (Not Equipped), ensuring simplicity in applications where an external brake is preferred. Designed for demanding industrial environments, it utilizes Surface Cooled technology to maintain optimal operating temperatures.

From a technical standpoint, the motor delivers a Nominal motor speed of 1500 min^-1 with a Continuous current at standstill rating of 42 (63)^5) A and a Continuous torque at standstill of 38 (57)^5) A. It can sustain a Maximum peak of pulse current of 195 A during dynamic load transitions. The Torque constant at 20 degrees C is specified at 1.010 Nm/A, supported by Windings inductance of 3.2 mH and a low Windings resistance at 20 degrees C of 0.176 ohm. A substantial Rotor moment of inertia of 230 x 10^-4 Kgm^2 allows for smooth acceleration profiles, while the motor’s mass of 59 kg provides stable mounting and reduced vibration.

Operational features include a >>Thermal time constant<< of 120 (90)^5) min, enabling prolonged load handling before thermal thresholds are reached. The Surface Cooled design efficiently dissipates heat under continuous duty, enhancing reliability and reducing maintenance intervals. The integrated D encoder feedback system ensures high-resolution position monitoring and rapid response to control signals, improving overall system precision. With a resilient mechanical and electrical architecture, the motor supports frequent start-stop cycles and intensive operation without performance degradation.

Integration is simplified through the standardized Side A power connector and compatibility with common Rexroth drive controllers. The motor’s form factor aligns with B05 and B14 mounting interfaces, facilitating retrofit into existing systems. Its versatile performance characteristics make it ideal for machine tools, packaging machinery, conveyor systems, and robotic automation. Engineers benefit from straightforward commissioning, precise control, and the ability to scale performance across diverse industrial applications.
