MAC112C-0-HD-4-C/130-A-0/WI520LV/S021

The Bosch Rexroth Indramat MAC112C-0-HD-4-C/130-A-0/WI520LV/S021 is a highly engineered member of the MAC AC Servo Motors series, embodying the precision and reliability Bosch Rexroth Indramat is renowned for. Designed as a MAC Permanent Magnet Motor, it features a robust power connector on Side A for streamlined installation and cabling. This unit is equipped with an incremental encoder with standard mounting and comes not equipped with a blocking brake, ensuring precise feedback while allowing system designers to select braking solutions tailored to their application. Weighing in at 48 kg, the motor strikes an optimal balance between structural rigidity and installation flexibility.

With a nominal motor speed of 2000 min^-1 and a continuous torque at standstill of 27.0 Nm (44.0 Nm peak^5)), this motor delivers smooth, high-precision motion control under varied load conditions. The continuous current at standstill of 41 A (67 A peak^5)) and a maximum peak of pulse current of 195 A ensure that transient demands are met without performance degradation. The motor’s torque constant at 20 degrees C of 0.730 Nm/A and windings inductance of 2.5 mH are optimized for rapid current-to-torque response, while the windings resistance at 20 degrees C of 0.150 ohm minimizes I^2R losses and contributes to overall system efficiency. The low rotor moment of inertia of 170 x 10^-4 Kgm^2 supports dynamic acceleration and deceleration profiles, making it suitable for cyclic or high-speed indexing tasks.

Operationally, the motor benefits from a thermal time constant of 100 min (75 min^5)), providing robust thermal stability in continuous-duty scenarios. The natural convection cooling approach negates the need for auxiliary fans, reducing maintenance and noise. A motor length designation of C and standardized motor size 112 facilitate integration into existing machine frames or custom mounts without extensive redesign. The inherent durability of the permanent magnet design ensures consistent performance with minimal cogging, and the precise encoder interface enables closed-loop control schemes for positional accuracy better than a few arc minutes.

Integration of the MAC112C-0-HD-4-C/130-A-0/WI520LV/S021 is straightforward in multi-axis systems, leveraging the standard incremental encoder mounting for compatibility with a wide range of motion controllers and drives. The absence of an integrated blocking brake simplifies mechanical interfaces when external braking solutions or electromagnetic clutches are preferred. This servo motor excels in industrial automation, robotics, packaging machinery, and other applications demanding high dynamic performance, precise torque delivery, and reliable long-term operation. With its combination of advanced electromechanical characteristics and flexible installation options, it represents an ideal choice for modern motion control systems.
