MAC112B-2-GD-4HF/130-B-0/WI520LV/S094

The MAC112B-2-GD-4HF/130-B-0/WI520LV/S094 unit from Bosch Rexroth Indramat is part of the MAC AC Servo Motors series, designed for demanding automation tasks. This permanent magnet motor features a power connector on Side B and includes an incremental encoder with standard mounting for high-resolution feedback. A built-in brake option is not equipped, making it ideal where motor holding is not required. The motor’s centering diameter of 130 mm supports both B05 and B14 flange designs for flexible integration.

In continuous operation, the Surface Cooled motor sustains a continuous current at standstill of 41 (75)^5) A and delivers a continuous torque at standstill of 16 (29)^5) A. It accelerates with a maximum peak of pulse current of 223 A up to a nominal motor speed of 3000 min^-1. The rotor moment of inertia of 120 x 10^-4 Kgm^2 balances responsive acceleration with load stability, while the thermal time constant of 90 (60)^5) min ensures predictable heating and cooldown cycles. A torque constant at 20 , degrees C of 0.430 Nm/A, coupled with a windings inductance of 1.2 mH and windings resistance at 20 , degrees C of 0.090 ohm, yields precise torque control and low electromagnetic interference. Weighing 36 kg, the compact Motor Size 112 and Motor Length B package simplifies mounting in space-constrained cabinets.

Engineers benefit from seamless integration with standard servo controllers and easy field installation thanks to the Side B power connector. The robust surface-cooled design and high thermal inertia guarantee reliable operation in cyclic and continuous-motion applications. Ideal for robotics, packaging, assembly, and conveyor systems, this servo motor combines accuracy, durability, and straightforward commissioning for optimized machine performance.
