MAC112B-0-GD-4-C/130-A-0/GR279XX/S021

The MAC112B-0-GD-4-C/130-A-0/GR279XX/S021, Bosch Rexroth Indramat, MAC AC Servo Motors series offers a high-performance AC servo solution optimized for dynamic positioning tasks. This MAC Permanent Magnet Motor features a power connector on Side A, integrates a Type B encoder, and ships with a Not Equipped blocking brake option. Designed to meet the rigorous DIN 40 050 standard, the robust housing ensures protection against dust, liquids, and external impacts. Its shielded contacts and conformal guard construction further safeguard internal components in the most demanding industrial environments.

The motor delivers a Continuous current at standstill of 41 A and generates a Continuous torque at standstill of 16 Nm, while supporting a Maximum peak of pulse current of 223 A for rapid acceleration demands. Rated for a Nominal motor speed of 3000 rpm, it balances high-speed response with precise control. The low Rotor moment of inertia of 120 x 10?? kgm^2 enables fast dynamic changes, and a Thermal time constant of 100 min allows sustained operation under thermal stress. Electrical characteristics include a Torque constant at 20 degrees C of 0.43 Nm/A, Windings inductance of 1.2 mH, and Windings resistance at 20 degrees C of 0.09 Ohm, ensuring predictable performance across the control range. With a Mass of 25 Kg and a compact Motor Size of 112 in Motor Length configuration B, the unit remains easy to install in space-constrained cabinets. Natural convection Cooling Type negates the need for auxiliary fans, enhancing reliability.

Engineers will appreciate seamless integration with DCS drive controllers and industry-standard motion networks, enabling versatile use in printing, packaging, robotics, machine tools, and handling systems. Lifetime-lubricated bearings combined with brushless design minimize maintenance and maximize uptime. Built-in thermoswitch protection monitors winding temperature, automatically interrupting power if thresholds are exceeded—ensuring safe, reliable operation across diverse applications.
