MAC112C-0-KD-4-C/130-A-1/DI520LV/S021

The Bosch Rexroth Indramat MAC112C-0-KD-4-C/130-A-1/DI520LV/S021 is a high-performance AC servo motor from the MAC AC Servo Motors series designed for precision motion control in demanding industrial settings. This MAC Permanent Magnet Motor features a continuous current at standstill of 31.0 A (49.0 A peak) and delivers a continuous torque at standstill of 28.0 Nm (44.0 Nm peak), enabling robust static holding and dynamic acceleration. Rated for a nominal motor speed of 1500 min⁻¹, the unit integrates a high-resolution incremental encoder with a standard blocking brake and robust C-encoder interface. With a rotor moment of inertia of 170 × 10⁻⁴ kg·m², the motor balances rapid response and controlled motion, while its mass of 48 kg and natural convection cooling allow straightforward installation without auxiliary cooling equipment. The incorporation of a power connector on Side A streamlines cabling and maintenance, making the MAC112C series ideal for retrofit and new-build systems alike.

Performance is underpinned by advanced electrical and mechanical parameters: the torque constant at 20 °C of 1.000 Nm/A yields predictable torque output per ampere, while the windings resistance at 20 °C of 0.270 Ω and windings inductance of 4.5 mH ensure precise current control and low electrical time constants. The motor sustains transient demands up to a maximum peak of pulse current of 141 A for short bursts, supporting rapid acceleration profiles. The thermal time constant of 100 min (75 min at overload) provides thermal stability under extended cycles, and the rugged blocking brake guarantees secure load holding. The high-resolution incremental encoder assembly—comprising a light source, glass code disk, optical sensor, and processing electronics—generates quadrature pulses and a Z-channel index for exact homing and repeatability. Integration with Rexroth’s TDM, KDS, and DSC controllers enables advanced fieldbus communication, real-time diagnostics, and automatic tuning routines to maximize throughput and minimize setup time.

Reliability is assured through robust materials and proven design heritage from Bosch Rexroth Indramat; the motor’s natural convection cooling and precision bearings contribute to long service life with minimal maintenance. Compact dimensions and standardized connectors facilitate seamless integration into textile machines, printing presses, CNC machining centers, automated assembly lines, and packaging equipment. In robotics and handling systems, the MAC112C series delivers smooth torque delivery and high positional accuracy, while applications in medical devices benefit from its low acoustic noise and clean operation. The motor’s compatibility with industry-standard drive platforms and optional accessories—such as filter modules and cable kits—ensures flexible system configuration. Overall, the MAC112C-0-KD-4-C/130-A-1/DI520LV/S021 excels in applications demanding precise control, dependable braking, and enduring performance.
