MAC112C-0-KD-4-C/130-B-0/WI520LV/S021

The Bosch Rexroth Indramat MAC112C-0-KD-4-C/130-B-0/WI520LV/S021 from the MAC AC Servo Motors series combines robust design with reliable performance, featuring a continuous current at standstill of 31.0 A (49.0 A peak) and a continuous torque at standstill of 28.0 Nm (44.0 Nm peak). This AC Servo Motor of motor size 112 and motor length C delivers a nominal motor speed of 1500 min^-1 under a natural convection cooling type regime. The motor architecture leverages a torque constant at 20 degrees C of 1.000 Nm/A for precise torque generation and ensures high power density in a compact form factor weighing 48 kg. Its winding assembly, optimized for industrial use, supports both incremental and incremental‐standard feedback without additional modifications.

The drive train excels in dynamic response thanks to a maximum peak of pulse current of 141 A and a rotor moment of inertia of 170 x 10^-4 Kgm^2, which balance acceleration and rigidity for demanding motion profiles. Thermal stability is maintained by a thermal time constant of 100 min (75 min under cyclic conditions), while electrical characteristics such as a windings inductance of 4.5 mH and a windings resistance at 20 degrees C of 0.270 ohm ensure predictable current-to-torque conversion. The seamless match between winding parameters and motor control electronics supports incremental encoder mounting (WI520LV) for high‐precision position feedback.

Engineered for ease of integration, the MAC112C motor features a standard centering diameter of 130 mm and a robust housing that requires no auxiliary fan, reducing maintenance points. The absence of a blocking brake simplifies the mechanical interface, while the natural convection cooling and IP-rated enclosure guarantee reliable operation in diverse industrial environments. Overall, this unit provides a high-performance, low-maintenance solution for precision automation tasks where smooth torque delivery and compact installation are critical.
