The Bosch Rexroth Indramat MAC112B-2-GD-4-C/130-A-1/WI524LV motor is a high-performance AC servo device in the MAC AC Servo Motors series that combines robust mechanical design with precise electronic control. Manufactured by Bosch Rexroth Indramat, this MAC Permanent Magnet Motor delivers consistent speed regulation and torque output for demanding industrial automation tasks. The design features a power connector on Side A and integrates an incremental encoder with standard mounting, enabling real-time, high-resolution feedback. A standard blocking brake is included to maintain static positions safely and reliably under power-off conditions. With its synchronous data transmission architecture, this motor ensures tight loop control and minimal latency in closed-loop applications.
This servo motor is defined by a comprehensive set of technical specifications that underpin its performance. It supports a Continuous current at standstill of 41 (75)^5) A and generates a Continuous torque at standstill of 16 (29)^5) Nm. The device handles a Maximum peak of pulse current of 223 A without degradation. It rotates at a Nominal motor speed of 3000 min^-1, driven by windings with Windings inductance of 1.2 mH and Windings resistance at 20 degrees C of 0.090 ohm. The Torque constant at 20 degrees C is 0.430 Nm/A, providing reliable torque output per ampere. Thermal management is characterized by a Thermal time constant of 90 (60)^5) min, and the rotor exhibits a Rotor moment of inertia of 120 x 10^-4 Kgm^2. Weighing 36 kg, this 112-size, B-length cooling unit utilizes a Surface Cooled design to maintain optimal operating temperatures.
In operational contexts, the MAC112B model delivers smooth acceleration and deceleration profiles, thanks to its high torque constant and low rotor inertia. The integrated incremental encoder ensures accurate position feedback for precise motion control, while the blocking brake provides 45 Nm of holding torque for static loads. Surface cooling and robust winding construction enable continuous duty cycles even under heavy load, and low electrical noise emission supports sensitive automation environments. Synchronous data transmission enhances responsiveness, reducing phase lag and improving system stability. The motor’s Compact 112 form factor and B-length housing facilitate easy mounting and alignment in multi-axis assemblies.
System integrators benefit from the MAC112B-2-GD-4-C/130-A-1/WI524LV’s compatibility with standard Rexroth drive controllers and PLC interfaces. Its standardized encoder mounting and power connection scheme on Side A simplify field installation and maintenance procedures. Target applications include assembly robots, CNC indexing tables, packaging machinery, and material handling systems where precision, repeatability, and dynamic response are critical. The combination of high torque density, closed-loop control, and integrated braking makes this motor ideal for industrial automation solutions requiring robust performance under continuous operation.
