MAC112B-0-LD-4-C/180-A-0/WI533LX/S011

The Bosch Rexroth Indramat MAC112B-0-LD-4-C/180-A-0/WI533LX/S011 belongs to the MAC AC Servo Motors series and combines a robust AC Servo Motor MAC design with a Motor Size 112 frame and Motor Length B profile. Engineered for seamless DCS drive integration, the unit delivers a continuous current at standstill of 26.3 A and a continuous torque at standstill of 17.5 Nm, ensuring consistent performance under load. Natural heat dissipation is achieved through Cooling Type Natural Convection, eliminating the need for auxiliary fans while maintaining operational stability. The motor’s compact yet sturdy construction underscores its suitability for demanding industrial environments.

Crafted for precision applications, this servo motor operates at a nominal motor speed of 2,000 rpm and can handle a maximum peak of pulse current of 130 A for rapid acceleration and dynamic load changes. Its torque constant at 20 degrees C of 0.74 Nm/A and low windings resistance at 20 degrees C of 0.26 Ohm translate electrical input directly into smooth mechanical output. With a windings inductance of 3.5 mH and a rotor moment of inertia of 120 x 10^-4 kgm^2, the motor offers tight speed regulation and quick transient response. A thermal time constant of 90 min allows for predictable thermal behavior under cyclic or continuous duty, while the mass of 36 Kg provides a balance between rigidity and manageable installation weight.

This servo motor’s combination of high torque density, precise encoder compatibility, and maintenance-free convection cooling makes it ideal for CNC machinery, robotics, and packaging systems. Its robust electrical and mechanical parameters ensure reliable performance in metalworking, material handling, and conveyor automation. The MAC112B motor stands out as a versatile solution for applications demanding efficiency, repeatability, and long service life.
