MAC112C-0-KD-4-C/130-B-1/DI524LV/S014

The MAC112C-0-KD-4-C/130-B-1/DI524LV/S014 motor by Bosch Rexroth Indramat is a high-performance actuator within the MAC AC Servo Motors series, designed to deliver precise and robust motion control in industrial applications. This unit features a Motor Size of 112 and a Motor Length of C, providing a compact footprint without sacrificing power density. At a Nominal motor speed of 1500 min^-1, the drive system achieves consistent rotational output, while the built-in AC Servo Motor architecture ensures responsive control loops. The motor’s continuous performance is rated at a Continuous current at standstill of 31.0 A (49.0 A peak) and a Continuous torque at standstill of 28.0 Nm (44.0 Nm peak), balancing torque generation with thermal management. With a Mass of 48 kg, this motor strikes an optimal power-to-weight ratio, facilitating integration into both new and existing installations.

Performance is further enhanced by a Maximum peak of pulse current of 141 A, enabling short-term overcurrent capability for rapid acceleration profiles. The rotor’s dynamic behavior is characterized by a Rotor moment of inertia of 170 x 10^-4 kg·m^2, which, combined with a Thermal time constant of 100 min (75 min under certain conditions), provides stable thermal regulation during continuous and intermittent operation. Efficiency gains are realized through a Torque constant at 20 degrees C of 1.000 Nm/A, supported by precise electromagnetic design. The motor winding is engineered with a Windings inductance of 4.5 mH and a Windings resistance at 20 degrees C of 0.270 Ω, ensuring rapid current response and minimal energy loss. Natural convection cooling maintains optimal operating temperature under heavy loads, while the encoder interface (C encoder) and tachofeedback deliver sub-millisecond position feedback for closed-loop stability.

Reliability is assured by a standard blocking brake providing 45 Nm of holding torque, guaranteeing secure stoppage and positional retention in safety-critical environments. The power connector on Side B allows flexible cabling orientations and simplifies installation in space-constrained machine frames. The motor’s robust construction and advanced thermal management support continuous duty cycles, making it well suited for assembly robots, handling systems, packaging lines, and CNC applications. With its combination of high torque density, precise feedback, and integrated braking, the MAC112C-0-KD-4-C/130-B-1/DI524LV/S014 delivers dependable performance and seamless integration in demanding industrial automation tasks.
