MAC112D-0-ED-1-B/130-A-1/J1250/S05

The MAC112D-0-ED-1-B/130-A-1/J1250/S05 is a high-performance AC Servo Motor in the renowned MAC Series by Bosch Rexroth Indramat, designed for precise motion control in demanding industrial applications. This permanent magnet synchronous motor, designated with Motor Size 112 and Motor Length D, delivers a compact footprint with a Mass of 59 kg and meets the stringent Protection Class IP65 standard for dust and water resistance. Featuring Natural Convection cooling, it achieves efficient heat dissipation without auxiliary fans or liquid cooling circuits. The motor incorporates electronic commutation and a brushless design to minimize wear and extend service intervals. With a Thermal time constant of 120 min, the MAC112D maintains stable operation over prolonged cycles.

Engineered for rapid-response automation, this servo motor offers a Continuous current at standstill of 63 A and generates a robust Continuous torque at standstill of 35 Nm to handle heavy load inertia. Its Nominal speed of 3000 min-1 supports high-throughput processes, while the Torque constant at 20°C of 0.620 Nm/A ensures predictable torque output per ampere. The windings exhibit a Winding Inductance of 1.3 mH and a Winding resistance at 20°C of 0.070 Ω, resulting in precise current control and minimal electrical losses. A Standard holding brake is integrated to provide a Holding torque of 40 Nm, securing the load in standstill conditions. Every parameter—from electrical time response to mechanical robustness—is calibrated to deliver smooth acceleration and deceleration profiles.

Built for seamless integration, the MAC112D interfaces with Bosch Rexroth’s TDM, KDS, and DSC drive controller series to form a synchronized drive system. Its brushless construction and IP65 sealing guarantee reliable operation in textile machines, transfer lines, packaging equipment, and CNC machine tools. The motor’s low inertia and high repeat-frequency capability support continuous start-stop cycles without performance degradation. In non-industrial environments, additional mains filtering may be required to suppress electromagnetic interference. With its proven durability and compatibility across a wide range of automation platforms, the MAC112D-0-ED-1-B/130-A-1/J1250/S05 servo motor delivers consistent precision and uptime in complex production settings.
