MAC112D-2-ED-4C/130-A-0/DI520/S05

The Bosch Rexroth Indramat MAC112D-2-ED-4C/130-A-0/DI520/S05 servo motor from the MAC AC Servo Motors series is engineered for demanding industrial automation applications. This AC servo motor features a robust protection rating of IP65 and operates at a rated speed of 3000 rpm. It delivers a continuous torque at standstill of 57 Nm and supports a continuous current at standstill of 102 A, ensuring consistent motion control under load. The unit’s mass of 59 kg provides stable mechanical coupling, while the durable housing coat of Black Prime Coat (RAL9005) offers long-term corrosion resistance. With an insulation class F design, the motor tolerates elevated winding temperatures for extended duty cycles.

Performance characteristics are optimized for precision and dynamic response. The motor’s torque constant of 0.620 Nm/A at 20 °C facilitates efficient torque generation, while the winding resistance of 0.070 ohms and winding inductance of 1.3 mH minimize electrical losses. A thermal time constant of 90 minutes ensures gradual heating, enhancing stability in continuous operation. The rotor’s moment of inertia of 230 x 10^-4 kg·m² balances acceleration demands with smooth deceleration profiles. Peak load capability is supported by a maximum peak of pulse current of 312 A, enabling rapid torque bursts for dynamic positioning tasks. The motor feedback options include tachofeedback and either mounted incremental or absolute encoder, delivering high-resolution velocity and position data.

Reliability and system integration are central to the MAC112D design. The motor’s type of cooling: surface cooling is complemented by an axial cooling system consuming 40/42 VA at 115 V AC, 50/60 Hz, with blower components rated IP24 (blower unit) and IP44 (blower motor). The robust IP65 protection rating guards against dust and water ingress in harsh environments. Installation versatility extends to altitudes up to 1000 meters above sea level without performance derating. Target applications include robotics, material handling systems, packaging machinery, and CNC platforms, where precision, durability, and seamless drive integration are paramount.
