MAC112C-0-HD-4-C/130-A-0/WI518LV/S021

The Bosch Rexroth Indramat MAC112C-0-HD-4-C/130-A-0/WI518LV/S021 is a high-performance member of the MAC AC Servo Motors series, designed for precision motion control in demanding industrial environments. This MAC Permanent Magnet Motor integrates an Incremental Encoder with Standard Mounting and features a power connector on Side A for streamlined connectivity. Its design emphasizes robustness and reliability, offering consistent torque output and minimal downtime. Engineered for applications that require both precise speed regulation and dynamic response, this motor delivers efficient motion control with minimal mechanical complexity.

Detailed technical specifications define the MAC112C motor’s capabilities. The motor achieves a nominal motor speed of 2000 min^-1, optimized for continuous operation at rated load. It supports a continuous current at standstill of 41 A (67 A peak)^5) and provides a continuous torque at standstill of 27.0 Nm (44.0 Nm peak)^5). Peak pulse currents reach 195 A, while the torque constant at 20°C of 0.730 Nm/A ensures precise torque production per ampere. The rotor’s inertia moment is 170 x 10^-4 Kgm^2, balancing rapid acceleration with controlled deceleration. Electrical characteristics include windings inductance of 2.5 mH and windings resistance at 20°C of 0.150 ohm, enabling predictable current draw and thermal behavior. With a thermal time constant of 100 min (75 min^5)), the motor sustains performance under extended loading. The assembly weighs 48 kg and adopts a natural convection cooling type for maintenance-free heat dissipation.

Operational features of the MAC112C-0-HD-4 variant focus on delivering repeatable, high-precision performance. The incremental encoder feedback loop provides real-time position and speed data, minimizing overshoot and enhancing dynamic response. Its built-in tachofeedback system maintains desired speed under variable load conditions, reducing energy consumption and wear. The absence of a blocking brake reduces mechanical friction, simplifies maintenance, and enhances continuous operation suitability. Natural convection cooling and the robust enclosure ensure stable performance across a wide temperature range, while the specified thermal time constant prevents thermal overload during sustained peak loads.

System integration is facilitated by the MAC series’ standardized mounting interfaces and compatible drive electronics. The Motor Size 112 and Motor Length C dimensions conform to industry modularity standards, easing retrofit and new-design installation efforts. Target applications include robotics, CNC machining, industrial automation cells, and other precision control systems requiring high torque density and reliable encoder feedback. With its combination of compact form factor, rigorous Bosch Rexroth Indramat quality standards, and advanced technical specifications, the MAC112C-0-HD-4-C/130-A-0/WI518LV/S021 is ideal for modern motion control architectures.
