MAC112B-1-LD-1-B/130-A-1/-I00625

The MAC112B-1-LD-1-B\/130-A-1\/-I00625 from Bosch Rexroth Indramat represents a robust addition to the MAC AC Servo Motors series, delivering high performance in a compact footprint. This AC servo motor operates at a nominal speed of 3000 min⁻¹ while providing a continuous torque at standstill of 35.0 Nm and a continuous current at standstill of 63.0 A. Weighing 59 kg, it balances power density with manageable mass, making it suitable for demanding industrial automation tasks. Its IP 65 protection category ensures reliable operation under harsh environmental conditions, safeguarding against dust ingress and water jets. Designed for seamless integration, this unit adheres to stringent quality standards set by Bosch Rexroth Indramat.

Technical sophistication is evident throughout the design, starting with a minimal winding resistance of 0.070 Ohm and a winding inductance of 1.3 mH to optimize electrical responsiveness. The motor’s torque constant at 20°C of 0.620 Nm/A and a voltage constant of tachogenerator rating 1.5/1000 V/min⁻¹ deliver precise feedback and efficient conversion of electrical input into mechanical output. With a maximum peak of pulse current rating of 312 A, the drive system can handle rapid transient loads without compromising stability. The rotor moment of inertia of 230 x 10⁻⁴ kgm² contributes to exceptional dynamic response, while its insulation classification of F supports continuous operation at elevated temperatures. This combination of electrical and mechanical parameters ensures the motor meets stringent performance demands in high-precision applications.

Operational reliability is further enhanced by a thermal time constant of 120 minutes, allowing sustained operation under heavy loads with predictable thermal behavior. The permissible ambient temperature range of 0 to +45 °C supports use in varied factory environments without derating. Surface cooling provides efficient heat dissipation, maintaining optimal temperature levels and reducing maintenance intervals. The motor’s Motor Size 112 and Motor Length B configuration ensure compatibility with standard mounting solutions, facilitating straightforward replacement or upgrades of existing systems. These operational features combine to deliver consistent torque delivery, low vibration, and quiet running, enhancing overall system uptime.

Integration into complex automation systems is simplified by the inclusion of a built-in tachogenerator, offering accurate speed feedback via its voltage constant of 1.5/1000 V/min⁻¹ output. The surface-cooled design aligns with common industrial control architectures, supporting both centralized and decentralized drive installations. This servo motor excels in applications such as CNC machining centers, packaging lines, and robotic assembly cells where precision motion control is critical. Leveraging Bosch Rexroth Indramat’s global support network, engineers can deploy the MAC112B-1-LD-1-B\/130-A-1\/-I00625 with confidence in performance, reliability, and long-term serviceability.
